Circuit Bent Goosebumps toy

More and more I get interested in circuit bending. I’m setting up a little place in the garage where I can start some soldering and modifying of old toys to create new sounds. Sounds I bit strange, and this video doesn’t fully do it justice (but it’s worth mentioning the monome 40h in the background, right?). Looking at the photos this looks like a crew I’d probably hang with.
