This is a quite amazing creation that blows away the cars, tractors and rudimentary aeroplanes that most of us manage when fiddling with a child's Lego collection. It's a physical synthesiser, using Lego mechanics to play a live track.
Built for the 2014 Audiograft music festival by student Alex Allmont, the Lego synth uses a mass of Technic pieces to trigger samples based on the classic acid sounds banged out by the Roland TB303. The resulting music's relatively hypnotic; watching the pegs and wheels turn in time to it is mesmerising. [Vimeo via Sick Chirpse]
