Coconut Run 19: Uber Tank
Swamp buggy model with attached caterpillar thread represents concept project of BT-2 russian tank speedy chassis ( http://www.aviarmor.net/TWW2/Tanks/US... ).
This is the most complex model - physical engine of Coconut Run flash program really suffers (FPS is about 11-13). Also it's quite moody since a lot of moving parts tends to tie in a knot.
The model made with high precision by AutoIt script (see the next video).
