INFO VISUALIZATION: You have to love Ian Albert. According to his website, he has "an obsession with high-resolution, high-fidelity digital images." He's not kidding either. He put together a, um, poster that displays every unicode character. Size: 22,017 × 42,807 pixels. Downloadable as a Bittorrent.
There are some other gems on his site as well, like the Ultima 7 map. (Never played that game, but now I kinda want to.) Worth a look.
