I think a really cool block would be one that would get the data from a SETI@home group.
If I had more knowledge I would attempt this but at this point I do not know how to accomplish the creation of such a block. It would be neat to present all of the groups data in one sweet little block for all to see.
If you have made a block like this one please let me know.
