Mr. Đức thắng Nguyễn (Duc Thang Nguyen) is an engineer from Vietnam. Since his retirement in 2002, he has being working on an amazing animated 3D catalog of mechanical contraptions.
Using Autodesk Inventor as a tool, he has documented over 1,700 mechanisms. All from gears, couplings, clutches, differentials to detailed examples of movement conversions. For every mechanism Nguyen has generated a corresponding animated YouTube video. These videos are an invaluable source to understand some of the more convoluted and challenging mechanisms. The video-clips portray a mesmerizing collection of kinetics sculptures on their own and can be enjoyed for their sheer aesthetic value.
