Reminds me of the Lissajous figure demonstrations at the Franklin Institute; the big old compound pendulum sand tables and the plate you could cover with sand and tne vibra with a rosined bow.

Boy, that place has really hit the skids in the process of becoming finacially viable and damage resistant to hordes of unsupervised brats. It's a microcosm of everything tha's bad about the educational establishment.

It used to be a temple to the sciences, now it's just about one stop above Sesame Place.
