So, while doing some youtube browsing I just stumbled across the work of Andrew Chase. I first looked at his work about a year ago and thought it was awesome. Having looked at it once again, I still think its awesome. Specifally, Im referring to his metal sculptures. These sculptures have a fully working skeleton inside built from gears and bearings etc so that the final model is fully poseable and should be able to move in any way that the real creature can. In fact, there are some awesome youtube videos of simple stop motion for some of the creatures.
