Piano Lightbox » minor9th.com
I’d like to make a piano which spews light, cleverly, depending on what keys are pressed. It should be fairly seamless and not overt, so the workings need to hide inside, but the basic premise is:
Someone plays the keys -> Some magic processing happens -> The music is interpreted, tastefully, in light form and slips out from above the keybed, over the top of the piano and beyond.
