Marshmallow Laser Forest
I helped Marshmallow Laser Feast do a large interactive music/laser installation at the STRP Biennale in Eindhoven earlier this year. It consisted of a forest of rods that came out of the ground with lasers on top of them. If you tapped one of the rods it would make a sound and the laser would light up.
They got me in to consult on the hardware, so I made some physical prototypes and we got Mike Harrison to make the final board. I also went out to help them install.
Here’s a link to the project page.
