wow, that black or white dots pic is kick-ASS, OR! i've seen optical illusions but none like that one, i really saw black dots inside the white ones and i couldn't make them go away!

anyways something really trippy you can do: download the latest version of WINAMP, play your favorite mp3's on it, and watch the visualization (sp?) take you to space in full-screen...much prettier than any media player visual shit
