I mentioned in this post that, having sketched an idea out in Processing, I was going to make it into a Scriptographer tool. Which I have now done. It’s not perfect, but it’s fun. It makes pretty-little-triangles. Attractive, but meaningless.
Here’s the Scriptographer script: prettyLittleTriangles.
Load in a source image from the menu and click start. It’ll draw the first triangle for you. Grab the yellow pencil tool from the bottom of your tool bar, and start clicking on the triangle to subdivide at will.
I’ve been testing it with images at 1200px x 800px, which seem to work well.
