I really was doing research for work when I found this Firefly website. I can't remember what keyword I was using to somehow pull up -- wait, it must have been gridlines.
I do remember how I got this map of Earth, however. It's so cool. The sunlight's moving.
(Here's the xkcd about Cadbury eggs... :) I wasn't looking that up for work, though. I wonder if Randall cooks with Kinder eggs, it'd have some potential for worse things than Cadbury.)
