Well, the creature creator has officially been released for a while now, and it's really fun (if you don't have it, go download the trial at http://www.spore.com/ftl).
Here's the place to post pictures / youtube vids of your creatures, and discuss the full game coming out on September 7th.
Ballrus
Dragonnake
Giant Head
Great Kappa
Klawbug
Piranha Plant (from Mario)
Spikogator
Spyclops
Stickman
Tribe Monster

If I do say so myself, I think that some of the names are pretty good
