Lantern screens and such

There are many ways to do this. I have been reading up on Islamic art patterns and get inspired by them. I got a picture of a pattern I like and I hand traced the outlines and figured out the geometry of the repeating pattern. In the post I link to I have the raw vector lines that I used to make the patterns so you can download that and see how I did it.

Do a search on tessellations and you will get all kinds of interesting patterns to work with.

Another possibility is to do a script, like Processing or Javascript.

I used this site and code to make some interesting stuff.

Here are some links to an older post that references the Processing. I installed the Processing platform and got some great images.
