most of them are fantastic i think..
but i acutally DONT like the new text ones unless theyre extremely funny and witty...because i judge t-shirts almost completely by the visual appeal of the graphic...
but right now a lot of the graphic tees are in that psychedlic art style, its really vibrant and almost whimsical lol..
favourite one would probably be
Threadless T-Shirts - Psychedelic Creatures by Simon Noynay - there are a LOT of shirts in this style now but this was out quite a while ago so i can say its still fresh heheh. :P
