I stumbled across this site, not particularly my forte, but it looked interesting. Not sure if other have been there before though.

Not seen that one before. This is carrying on from the success of Galaxy Zoo that used peoples brains/eyes to spot galaxies.

There is also Galaxy Zoo Mergers and Ice Hunters.

I have done a few hours on Galaxy Zoo but not the others. Good find. I will have a closer look when I'm not doing anything.

I did wonder if this would be right up your strata Snowcrash, but I wasn't sure if it was for a younger clientele. Post your feed-back when you have time.
