Slider Crank Animation

[HookedOnHalo]

I'm looking for an animation of a slider-crank mechanism. I'd like one that I can change the variable of the crank and connecting rod so show the change in the motion. I've Googled and found some animations but non that allow me to change the parameters. I did find site that uses Ch Standard Edition but I can't get it to work with Windows Vista.
