Sound Dough

Make a glorious racket that obeys the laws of an intricate visual entanglement with Le Ciel Est Bleu's La Pâte à Son:

" The Pâte à Son (Sound Dough) is a sound toy and compositional tool conceived to encourage musical experimentation. Drag instruments, switches, and transporter pipes from the conveyor belt to the checkerboard above to make music. Rotate the pieces. Choose a melody. Change pitch, tempo and volume to fine-tune your composition. "
