Sadly it hasn't got much info, but what I see is a nice Eurorack module, controlled by a wooden custom-made (DIY?) controller box with faders, buttons and a joystick.
The video is shot on a mobile phone in portrait-mode and the video isn't very sharp, but I like the sound-effects that are created...
Video: Like Forbidden Planet
