3D was all the rage at this years CES.  Now you can get in on the action without having to wear those silly glasses.  This questionably useful but definitely fun application turns your desktop into a three dimensional workspace.Here you can pin documents to the walls, create stacks, or just make your icons bump into each other.  It’s been kicking around for PC’s for a while now, but was just released for Mac earlier in the week.  If you are interested in getting your bump on, grab the software here.
