, the designer who created a 'Home Disco
' out of lasers and a smoke machine, has unveiled his latest installation: a laser harp
. Consisting of a black obelisk surrounded by a cage of laser beams, Waldemeyer's harp uses light sensors and an Open Frameworks app to create sounds whenever a person interacts with the laser field. Waldemeyer's "weird and wonderful
" soundscape is comprised of sirens and alarms, which are looped and woven together to form a cocoon of ominous space.
