This is a really interesting piece of gear called the Microphonic Soundbox that was released at Superbooth 2017 during the weekend of April 20th-22nd in Berlin at the Fez.
According to Leaf Audio this machine came into fruition:
"When I started experimental music back in the 90ties, I built myself an instrument which became the trademark sound of my project and sound design work. Now we re-created this instrument as a DIY kit for our workshops. In the video clip you see the prototype and hear sounds based on this instrument. Will be available from this summer."
Looking forward to reading more about this and hopefully hearing one in person!
