I've just discovered this website, and i am amazed at the level of work that goes into some of these abstract images. (My favourite!) I'm trying to figure out how to make one myself and hopefully, if it turns out, post it. I have a VERY limited program (picture viewer) where I can adjust coloring, contrast, etc. I would love to be able to do some of the stuff you guys are doing, but with which program? I realize most of you use Photoshop, but that looks like it's a Mac program and I, unfortunately, use Windows. Please help me!
