colours:

RGB
BW
CMY

These are and will probably always be prototype versions - BW and CMY will run as fast as your computer/browser combination and settings will allow - there is no definitive version.

Since this was originated in 2003 browser speeds and software behaviour have changed considerably - it's now (2014) impossibly fast on common browsers Firefox and Safari*.  Google Chrome's cache software gets confused, the colour changes become random and eventually seem to freeze.




* Safari 1.0 became available in 2003, Firefox 1.0 2004, Chrome 5.0 (the first non-beta for all platforms) 2009
