This is the Drift Box from REON co.,Ltd in osaka Japan. This video was previously availble on Youtubem but now we can see it in all its crazy high qaulity glory via Vimeo.
It creates complex cross modulations between two VCOs with a joystick control of various parameters. Oh yeah and its inventor Yamadub - a sound designer for games - with a wicked website ( I hope this is the guy who invented it too) is completely hatstand. Who needs a better reason to want to buy one?
There is a site with it listed at 37,800 Yen, but no firther information was available.
