Pentagons, ebb and flow

Pentagons, ebb and flow

I figure out how to do things, then I forget.

Making a GiF in Photoshop CS6 from artboards created in Adobe Illustrator is one of those things that I have to relearn every few months. I always panic when I have to learn it again. This post is mostly for me, to help me remember. Unless  this is something you want to do, just enjoy the pictures, especially the one at the bottom of this post.

Pentagons converging in color

Most of the GIF’s I’ve made have something to do with shape transformations. For instance, I’ve done a bunch with pentagons converging towards the center. I start with basic outlines then add effects. This post is about creating the gif from the artboards, not about making the images for the artboards. I leave that for you to figure out. But to give you an idea of my workflow, so that it makes sense for the rest of the post, here’s a screenshot of what one of my sets of artboards look like:

 

48 artboards

49 artboards

After I am happy with the Illustrator files I save, label and close my AI file.

Next, I open this Adobe Illustrator file in Photoshop. Since the AI file has lots of art boards. a box, which is labeled “import PDF” pops-up in the middle of my Photoshop workspace. Just ignore the reference to the pdf. Make sure the Pages option is picked. Pick your resolution. By default it’s at 300. Depending on my image, I sometimes can’t get a 300 resolution to save. I usually change this to 72.

Nothing is to scale here. Just highlighlighting what's needed

To get ALL of the AI artboards to open SHIFt-CLICK the first and the last pages that are loaded in that little window. This will select all the artboards. Press OK (which I forgot to draw, but it’s in the lower right hand corner of the box).

Once the layers panel is full of your images you will need to close them. Oh, this is when I remember that I need to put a new file on my desktop, labeled New Gif. So make that now.

THEN CloseAll your files using the CloseAll command under the file menu.  A menu will come up, you tell it to SAVE and check the box that says apply to all, pick that New Gif file you made to save the images in, and, one by one, they will go into the folder, and you have to press save for each image as it goes in.

One Artboard Image

NOW OPEN your new gif folder in BRIDGE. Bridge is a great program that is packaged with Photoshop. SELECT ALL the artboards. At the top of the Bridges workspace go to Tools>Photoshop>Load Files in Photoshop layers.

Now sit back and wait as the Photoshop’s layers are populated with the artboards.

Almost done.

Next, make sure the Timeline option in checked under Window. At the center of the bottom of the workspace there is a box. Choose then  click on Create Frame Animation. One of the artboards will appear on the timeline. Open the fly-out menu on the timeline. Click: Make Frame From Layers (this is the 11th item on the list, and will only show up if Create Frame Animation has been clicked,  not merely chosen).

The timeline will populate, probably backwards. If so, click Reverse Frames on the fly-out menu.

The positions of all these things that need to be clicked can be found in that drawing above.

The Gif is now basically done. The timing can be changed by clicking on the sec option below the frame. Shift click two frames to select everything between them.

NOW SAVING is a whole other thing.

Click on SAVE FOR WEB under the file menu. Choose the 2 (or 4) up tab on the upper left of the save box. On the right hand side of the save box JPEG will probably be in the second box from the top. Change this to GIF. Choose the file size you want to save. I usually pick the 2nd to the biggest file. Click Save, name your file and be proud.

Here’s the one I made last night:

Present from Angela

My daughter gave me an dodecahedron. Each of its 12  faces holds 25 sheets of sticky note papers. I’ve been doodling on them.

With my family around this week this is the perfect thing for me to be playing around with. As I drew on the sides it was nice to know that when I finished all 12 sides that I could peel off the pentagonal sides and start all over again.

But what should I do with the first set?

What I’ve been doing is sticking them on black paper. Then I filled the sides of the shape again. And again. And again.

Lots of Pentagons

So far I’ve filled up the sides four times.

This is a perfect project for right now. While we are sitting around together talking, having coffee, or just being in each others’ presence, I can be using my colors.

I don’t intend to fill all 300 pentagons from my 12-sided shape, but I think I’ll do a good bit more.

Am satisfied to be finishing off this year with this construction

Happy New Years to all. May your New Year be filled with curiosity, exploration, and color.

Last year, on December 24, I posted a page of decorative papers I had created to do some last minute wrapping. To make the papers I lifted images from pages and posts made by people whose work I love, so, naturally, I loved the papers. It was such a pleasure to do that I’m doing it again.

See the PDF at the bottom of the post to get the best copies.

Here’s an exquisite doodle by Dan Anderson. Of this, he indicated that he didn’t really know what was going on with the creation of this graphic….which is how I usually feel about everything I do.

The page above is based off a graphic by Simon Gregg. A big part of the reason I picked this image is that it is part of a post that I really loved reading, https://seekecho.blogspot.fr/2017/12/nicomachuss-theorem.html

Suzanne Von Oy created a Desmos graph, which showed cows in a tornado. It was so silly that I, of course, had to play around with  it. That middle, green swirl in the picture above, is suppose to be kind of like a Christmas Tree with cow ornaments. (don’t judge me)

Here’s another image that I chose based on how much I liked the post that it is part of. There were all sorts of wild shapes associated with this Lawler family post, but I like how rotating just one of the images made this fun pattern.

When I saw this image stars-in-circles posted by Malke Rosenfeld, it just knocked my socks off.  Note the link in the caption, it says Star-o-Rama and how to make them!

It was unusually hard to figure out which of Martin Holthman mathart images to play with, as, lately, he has been having way too much fun making cool stuff. .Finally picked out this,  because it was not only awesome, but also seasonally snowflakish.

I discovered the graphing program Desmos shortly after it came on-line. I’m not fluent enough in math to make amazing graphics with it (yet?).  Geogebra has been around for, well, I don’t know how long. I haven’t spent much time with it, but John Golden has spent a great deal of time with it. I really couldn’t decide which of his images to use, so I chose two. I considered chosing three, but I’ll save that third one for another project. I think that wrapping a small package with these undulating black and white lines will look really great. I’m especially looking forward to using this one.

What’s the point of making mathy wrapping paper without some rhombic tori? No point at all. So here you have them, thanks to Mr. Golden.

If you want to print any or all of these papers,  I thin that the best way to do it is from a PDF.

Here’ the PDF Wrapping Paper 2017 . All nine images are here, but you can choose to print just the ones you need today using the dialog box on your printer.

Happy wrapping.

Alison and her Milk Cartons

December 20, 2017

The Star that Nancy picked out to keep

The Star that my friend Nancy picked out to keep

The morning that I started this post I saw a series of photos tweeted out by Alison Martin. She’s been making some wondrous constructions using milk cartons. Here are two of the five tweets that caught my attention:

My attention was riveted on the fact that she had thought of this very accessible way to make slices of squares which she could then skew to make a veritable symphony of constructions. (Yes, am mixing metaphors. Will welcome edits…)

Sadly, our milk comes in glass bottles.

Also, since I do projects with students in schools, I have this thing about wanting to make everything from regular copy paper.

Paper Starbursts made from regular copy paper

Paper Starbursts made from regular copy paper

As I worked out how to create these starbursts I thought about the methods I use of working with paper that are not obvious. I made a video, in which I’m talking the whole way through, pointing out details of working with paper.

 

 

Here are some photos which repeat bits of what I’m showing in the video.

Not exactly a milk carton

Not exactly a milk carton, but it has a square end. Cuboid? Rectangular Prism?

Start with folding a tab. Next, ignoring the tab, fold a piece of regular copy paper into fourths, and then glue to the tab to make a shape with a square end.

Slice and glue

Slice and glue

Slice off a strip. Now, it’s not obvious how to continue, so don’t start slicing lots of strips. Just STOP after one slice.

Spread glue on one section of the tube (the part in the photo that has pencil lines on it)  then glue down that one slice of the paper at the edge of the tube. See photo below.

First Ray

First Ray, glued

Cut away another slice from the glued section, the same width as the slice that’s been glued on to it. Repeat and repeat…

A series of Rays

A series of Rays

…until you have 5 or 6 or 7 or 8 or however many rays you want or have materials for. I usually make 7 rays. Then glue the parts together that make them stay fully rotated.

The inside stars are a bit different to do. Make that shape with the square end again, but the width of the of this paper with should be about a third thinner than the paper you started with. (My first paper was 8 1/2″ wide, this second part was done with 5 1/2″ wide paper)

I’m going to let you figure out where the glue will go: this is pretty obvious.

What’s not so obvious is how to get the ray nicely placed.

What you do it this:

Placing an inner ray

Placing an inner ray

Splay open the big ray, slide in the small ray, then….(this is important, not obvious!)…

Sandwiching squeeze

...squeeze the neighboring rays together, which makes all layers align just right.

After making this inner layer of rays, if you want to make an even more inner layer of rays, don’t bother with making a closed shape with a tab, just fold paper into fourths.

See, like this.

Now here’s something I wasn’t expecting: they stand up by themselves.

And they stack.

(Watch the video. To the end. It’s much better than this post.)
