[ale] [WAY OT]Putting a motor on a rocking chair

[tfreeman at intel.digichem.net]

I'm not much of an engineer, and I get really get weirded out by hacking 
furniture.

OTOH, gear down the electric motor, and work the chair with an eccentric 
cam. Let the cam rock the chair by acting against something on the 
floor. Figuring out how to smoothly vary the eccentricity of the cam is an 
exercise for the reader...

Another approach, probably easier on the floor, would be to oscilate a 
mass below the chair. Run the mass back & forth on drawer rails (think the 
wheeled things on the drawer of a filing cabinet).
