Well,first ya get some acid..... Erowid had a section devoted to the art,you may find some info on there. Other than that,I'm not sure.... http://www.erowid.org/
I did a search and came up with this link specifically...I didn't read the entire thing,so I'm not sure if it will help you or not... http://www.erowid.org/culture/art/art_article1.shtml
my suggestion is to get yourself into a good creative place both physically and head space, take some fun substences, get comfortable with them and let it flow right out of you. it works for me
Acid is like taking a 4 year art program in one experience.... you learn FLOW... since then everything has been much more aesthetically pleasing and my art is more vibrant and has more flow... its great for the abstract artist looking for flow, it shows you flow... everything melts into the paper/canvas wonderfully
