"Join five modellers from London VFX house Framestore at 1-2PM on 27th September for one of their weekly "Lunchcrunch" sessions live from ZED. See how they sculpt a creature within one hour on the theme of "Unleash The Beast" using Autodesk's Mudbox. From a primitive starting point to a fully-fledged character - come and be inspired.
So I ended up with this odd Tribal lizardy dude.
