Reader Mathew Lippincott (check out his mutoscope) points us to Kinematic Models for design (KMODDL), an open access, multimedia resource for learning & teaching about kinematics and the history & theory of machines.
The core of this wonderful museum is the Reuleaux collection of mechanisms and machines, a set of 19th century models built to demonstrate the elements of machine motion (more collections here). Also of interest are the tutorials and this extensive list of online references.
KMODDL also has 3D-printable models (see the multimedia section) and some of these have stereolithography files. They can be viewed with Meshlab. Thank you, Mathew!
