Interactive Sangaku

I made these ages ago (1999) as part of a university project. If you want to find out more about Sangaku Tony Rothman's 'Japanese Temple Geometry' from Scientific American is an excellent place to start (I pinched a couple of the examples from that article).

Anyway, the idea here was to illustate the principles behind the form of some popular Sangaku. Somewhat mixed results I think. You'll need the Java plugin for your browser (natch). -T
