i have been messing around with apophysis (apophysis-j) for some days now, and this is one of the best results i have had.
well, some people have not figured out why i named it snake.. have you? :P
the full resolution version (1680x1050) is available for download and fits well as a background for a 19"w screen ;)
ps: if you want it in a higher resolution, just send me a message
