I made a tetratetraflexagon for my wedding program. I ended up making a script to use ImageMagick to convert four images into two images suitable for printing on both sides of an 8.5"x11" sheet of paper. The scripts, example images, and instructions are here:

The recursive card you linked (link broken) is very impressive as well:

The concept is one thing but the execution takes it to another level.

I did notice the link was broken, but didn't want to wait until I had time to fix it before commenting. I've fixed it and a couple of other ones. Thanks.

Thanks for the instructions. I'm going to borrow them but I'll credit you as my source (linking to the webpage.)
