KMODDL is a collection of mechanical models and related resources for teaching the principles of kinematics--the geometry of pure motion. The core of KMODDL is the Reuleaux Collection of Mechanisms and Machines, an important collection of 19th-century machine elements held by Cornell's Sibley School of Mechanical and Aerospace Engineering.

I had this as a bookmark for a while. I thought I'd share it as I thought someone might find the various models interesting. Click on the 'Models' section for the various models, some have some pretty neat movies of the models in motion.
