I found this page, which appears to be fairly old, but its new to me, which means odds are its new to someone else too.

Its basically a page that allows you to look at a huge number of screenshots of colorschemes off of Vim.org at the same time. Be fair warned, it will suck massive bandwidth and be super slow on non-broadband connections. Other than that its great fun to look around.
