That's a Synthesizers.com (
http://www.synthesizers.com) modular synth - kind of like a Moog modular, only made this year instead of in the 70's. Modulars are cool - each bit does something different, and you design sounds by patching cables between the bits to make up a signal path.
I used to lust after a large modular rig, and actually still do a bit, but then I got a Nord Micro Modular (
http://www.clavia.com), which basically fulfilled all my needs. Same idea, only virtual, so you can design your sounds on the computer, then disconnect it and just bring the (VHS tape-sized) hardware out to shows. Better yet, you don't have to repatch the whole system to get a new sound.. :)
IMHO, the synthesizers.com stuff is fantastic, but pretty much pitched at synthesists and hobbyists, the kind of people where if synths were cars, they'd be driving an MG.
Now this is a lustworthy synthesizer:

one day, in the not-too-distant future, I will own a G2... I love my first-gen Nord Modular to death, but the Nord Modular G2 is *sick*... if you know synthesis, you can make pretty much any sound imagineable...
