There's an interactive exhibit in the lobby of the New York Hall of Science that lets you deform a blob of this shiny goo. It's a lot of fun.

Thought of exactly the same exhibit -- love that thing! Worth a stop into NYHS to play with it. I immediately wanted to make one and I'm psyched to see on HN. Evidently it originally had buttons to control the charge, then curators upgraded it with the more tactile wheel controllers.
