Heh. My roommate (in NYC) at the time was involved-enough in this that one of the actual "devices" appeared in our apartment a few weeks later and surreptitiously remained for many years, fully working in its Lite-brite/LED glory.

It made for an excellent conversation piece for those that knew, and a weird piece of LED art for those that didn't.

Edit: I found pictures! Sorry they were shot on a potatocam (2008 era) but here she is:
