I have started putting some of my alien art on clothing and whatnot available at zazzle.com. Thanks to 
I will be putting more up soon but so far I have some leggings and shirts. I really like how this psychedelic mandala mirror looks on leggings!
You may remember that design, I posted some variants of it in this post. The original base image was my own macro photography of morel mushrooms :)
Another variant of that design on a women's tank top:
And on a men's shirt:
It also looks really cool on a throw pillow if I do say so myself :)
I have a ton of alien art back catalog to go through with an eye toward putting on clothing and other stuff. If you have any requests of a type of item you would like to see with my art on it, please let me know. Also if you know any other alternatives to zazzle.com, let me know - zazzle is easy to use and has a lot of options but I didn't really do much searching for alternatives, and the prices seem a little steep to me so please let me know if you there are better sites out there for this kind of thing!
much love - Carl "Alien Eyeball" Gnash
