Okay, so, various geek toys to date:
The Vigenere Cipher — part of this semester's conference project.
Relativity Calculator — just a silly E=mc2 thing.
Preston's Law — one of many, many ridiculous language toys I've made.
Colorgene — a strange, half-done RGB color breeding system. Just check two colors of your choice and click on "mate" to see what child colors they produce. (Tip: in the world of Colorgene, same-sex relationships do indeed produce offspring.)
Prime Number Finder — another half-done toy, this one to find all prime numbers below a certain number (maximum of 5000). To find a prime add "?n=blah" to the URL, where "blah" is the maximum number in question (e.g., http://somniloquy.org/misc/primes.php?n=525).
A much more substantial entry later, after I smoke and fraternize for awhile.
