I love nerd humor, but nerds predate the current "geeks are sexy" trend. Old school nerds FTW, nothing but. Besides that I just dig clever humor and amazing natural pictures. Bonus points for awesome band references.
"This view of Jupiter's Great Red Spot and its surroundings was obtained by Voyager 1 on February 25, 1979, when the spacecraft was 9.2 million km (5.7 million mi) from Jupiter. Cloud details as small as 160 km (99 mi) (100 mi) across can be seen here. The colorful, wavy cloud pattern to the left of the Red Spot is a region of extraordinarily complex and variable wave motion. To give a sense of Jupiter's scale, the white oval storm directly below the Great Red Spot is approximately the same diameter as Earth."
