Things have been a bit slow on the AE front here lately, so I thought I'd post something here that I found at CGTalk that I thought was pretty friggin amazing!
Rigging an IK character in AE using expressions!

That first link is Mr. Dan Ebberts' first crack at IK in AE. He later updated it and made this:

So there ya go!
Also, some of you may be aware that the new AE CS3 that's about to come out has a new feature called Puppet in it. Bob Donlon has a GREAT little tutorial of it in action on his blog site. Will probably make Ebberts' things obsolete, since it looks UNBELIEVABLY easy to set up!

anyway, if you haven't seen any of this stuff, it's all pretty interesting. If you have, I've bored you profusely by now.
