I’m a big fan of fractals, starting with discovering Fractint while filecrawling on a BBS back in the day, then naming my online “geek boutique” after them, then creating a paper toy named “Mandlebot”. Here’s a cool documentary on fractals by Nova: “Hunting the Hidden Dimension.”
Here’s a paper toy robot that I designed for Fractalspin.com, Mandelbot. Just download the PDF (email address required), print it out on cardstock or heavy paper, cut him out with an X-acto knife and then glue or tape him together.
He’s also featured on the back of a 5.5 x 8.5″ postcard featuring items from Fractalspin, although the gloss coating means you’d have to use super glue or a similar adhesive to get him to stick together (printer’s error *shrug*), and it will look nicer if you lightly score the fold lines before putting it together.
