Now this is cool: GalaxyZoo. I love participatory science (I was an early user of SETI@Home and have been running LIGO’s version for awhile as well). Every time I do something like this I feel that small tug pulling me back toward cosmology.
Actually, lately, I’ve been working on expanding upon some work on quantum gravity by the venerable Quantum Pontiff. In essence, he used wormholes as models for quantum computational processes. In picking up where he left off, I get to do quantum information and some cosmology at the same time!
