I recently left my CG supervisor chair at Snowball|VFX (http://www.snowballvfx.com), and started studying filmmaking. After shooting a few live-action shorts during the first semester I felt a shortage of VFX in my blood, and decided that as soon as the semester break starts I'll make a couple of tracking exercises to refresh my memory. It was supposed to be just camera tracking, with the usual floating statue or ball or whatever... What can I say? I got a *little* carried away.
Had loads of fun though, too bad I didn't quite finish it yet.
