Take a look at a little hypertext project I made almost a decade ago to explain and demonstrate aspects of ergodic design. This supplements the material in Mark Bernstein’s Hypertext Gardens, which you’ve already read. Download the ZIP, extract it, and double-click “grasshopper.html”
The idea for the project was to ergodicize a poem in a way that amplifies its message. This hypertext is based on an e.e. cummings’s poem!
