Anyone who has the Spore creature creator knows that you can download other peoples' creations to see in your Sporepedia, which is basically a collection of creatures made by you and by Maxis.
Just an idea, but I think it would be cool if when you made cool creature, you submitted an animated GIF of it to a stickied topic and we called the collection of everyone's creatures the ZFGC Sporepedia. Just an idea.
