One of my recent personal projects is R2D2. I'm pretty much done with the exterior model and texture, but my goal is to also create some of the inner tools he has. I've created the exterior with separate panels to open so I can have his arms and other paraphernalia animate.

Once I've completed his model and texture, I will rig him in a way to, hopefully, not only function, but project some life into his movements creating lifelike animations.
