Relativity

Dammit, I worked on this for a good half hour and it still didn't turn out quite the way I wanted. Really, I should just pirate a version of PhotoShop and install it here on my work compy, but that's so much hassle, and they'd yell at me. Ugh. Just... just try to imagine it, okay? Someday I'll go back through and fix the ones that need some serious fixing...
