Makes you wish you had your own neutral-buoyancy growth tank to sleep in, doesn't it? Some clones have all the luck. Anyway for future reference, that drawing can be found in the episode 13 gallery; you get to the galleries from the "episodes" link on the site's top menu.
A thoughtful reader on Facebook linked me to a nifty CG video from the American Museum of Natural History that illustrates the relative size of the known universe, kinda:
There have been videos doing that sort of thing for years, but this one is nice in a number of ways: a) labels distances in terms of the speed of light, b) nice pretty views of the dusty band of the Milky Way (and A* hidden inside it), and c) the positions and sizes of objects are actually based on real data. I'd have liked them to have rendered the local cluster of galaxies as they might actually look, rather than just as green dots, but still, a nice video.
