@futzle hi yes hello I was part of an art project that made use of this idea and I think of it every time I see groups of blinky lights ^_^

we ended up building our own lights and controllers and firmware for it, mostly because they would also - about every 10 minutes - display the speed of a seismic wave thru that particular soil geology https://github.com/ArdentHeavyIndustries/straightedge-gps-firmware
@bouncinglime @futzle that's really wild!
