Kromwell, keep an eye out on LHC's main page, particularly the server status bit on top. Right now it is showing:
Server Status

Up, out of work
18554 workunits in progress
When the number of workunits in progress reaches zero, it won't be long until a new cycle of work is started and they release about a hundred thousand new workunits.
In the meantime, there's plenty of other projects out there to play with.

What's your favorite so far?
