This is 3dPd! It's a physical modular synthesizer based on Pd and Arduino that I have been developing for a long time. It is finally ready and the code is up on GitHub!
I will upload the circuit designs and a wiki for building modules in the next few days...
Hope you like it and some of you will build one yourselves!
Here's a demo of it:
