Rorschmap
rorschmap is pretty awesome:

The word “kaleidoscope” is derived from the Ancient Greek καλ(ός) (beauty, beautiful), είδο(ς) (form, shape) and -σκόπιο (tool for examination)—hence “observer of beautiful forms”. It was invented by Sir David Brewster in 1815-17. Brewster was also active in the development of the lighthouse; both things were byproducts of his researches into optics. The light, refracted, serves both beauty and safety, both aesthetics and cartography.
