In the last video i mentioned an idea on laser cutting Music Box punch cards, four days later a group of software developers had done it! Check out the prototype software they have created:

The Marble Machine took 16 months to build and 2 hours to take apart.

I took the boat to mainland to disassemble the first Marble Machine. The Machine is going to the fantastic Speelklook Museum in Utrecht, Holland!

To get the marbles to hit the bass strings accurately on the Marble Machine X we designed the first 3D printed part for the machine!
