Has anyone played with the spore creature creator yet?

A couple of days ago a demo was released for the highly anticipated upcoming game spore. The demo just lets you play around with 25% of the available content, but if you pay 10$ you can get 75%. I played around with the demo for a bit, and made this hidious beast , but its amazing to see some of the things people make. For those of you who’ve played around with it, what do you think?
