  These are like the new, digital version of Reuleaux Models. i think Cornell has the largest collection. No animations, but certainly videos of the machines/models in action.
  For Example:

  The constant velocity joint remains the same rpm instead of a Cardan joint http://en.wikipedia.org/wiki/Universal_joint - there you need two joints to compensate the fault.

  Here is a video explaining how a lifter works in the injection molding process. Lifters are used to create some undercut features, with some limitations. Very helpful for some walks of designers trying to wrap their head around this process!

  A CV joint is what every front wheel drive car has to deliver power to the front wheels while allowing them to steer. It basically allows for a bend in a drive shaft that can actively change angle while consistently delivering power to the wheel. They are the things that wear out a lot and start creaking and squealing and aren't cheap to fix.

  Spectacular.
  
  Sometimes I feel smart, not now. Though I'm made a little nervous by the 'Skrinching' of the ammo when the gunpowder is packed in.

  Whilst studying for my A level in Design and Technology we used a program that explained and demonstrated how blow moulding, vacuum forming and many other types of manufacture were done, you could change the speed of the animation and cycle through it step by step. Here's a gif of how blow moulding works:

  We use this website at school in out DT lessons, they have gif's of pretty much every production process.
  
  This is the page with the links to the processes;

  A constant velocity joint connects a front wheel drive cars wheels to the transmission. It allows for independent movement of the wheel in relation to the transmission while maintaining connection.

  There is an Aluminum Superforming site that has some similar animations for the various ways they achieve their process

  Constant Velocity Joints are used in front-wheel drive vehicles to connect engine to wheels, to allow front wheels to turn, while receiving torque from the engine.

  I know this is not a mechanical movement, but it was a great GIF explaining PI

  They are in flash instead of being in GIF, but this site that my professor showed me has some nice animations showing basic manufacturing processes.

  RE the constant velocity joint: this simple but ingenious mechanism was the enabling technology for front wheel drive cars. A subtle but critical point about universal joints (an older, similar mechanism) which among other things allows the drive shaft in a rear engine car to pivot: the output velocity is not constant relative to the input velocity. This is not critical at the small angles or motion in a rear wheel drive setup (caused by suspension travel up and down), but with the high angles needed to turn the front wheels to steer a car, it would be. Thus the CV joint allowed the engine to power the front wheels for the first time.

  The constant velocity joint looks as if it will provide torque to a secondary axis, whatever its angle to the primary axis is, within reason. A right angle, or close, would be impossible I believe.

  Constant Velocity Joint= CV Joint most commonly in automobiles for front wheel drive and all wheel drive applications.

  If you drive a front wheel drive car you have a couple constant velocity joints!
  
  Cool stuff!
