The Soundplane from Madrona Labs[0] certainly merits a mention here. Pairs exceptionally well with their software synths Kaivo (physical modeling and granular synthesis) and Aalto (the closest thing to a Buchla in VST form).
I kind of assume at this point that most people who have an interest in this sort of thing know about monome[1], though I was surprised that there hasn't been more interest from HN in their most recent release, aleph[2], a (mostly) open source sound computer that can interface with just about anything that produces sound, cv, or bits.
