The first thing I had for this project was a series of shrieking speakers that shrieked harmonically, the frequencies of which could be raised and lowered with a potentiometer.
I wanted to make a series of tentacles that vacuum pumps would undulate uncomfortably, and would scream when touched. However, depression was kicking my ass this week and I could barely keep lucid enough to make sense of code at all. I ended up working with a heart rate monitor because it required less extra steps to make something spooky, because awareness of your own blood running through you is inherently creepy.
I wanted to have a wide variety of subtle atmospheric effects surrounding an alter-like sculpture, which would raise to a more anxiety inducing crescendo if they were reading someone’s rapid heart-rate. Blinking LED eyes were to be a single element, not the central ones, but this is what I ended up with.
