Sounds like a great idea with the 3d graphics program. Looking forward to seeing the final results :-D

Wow you seem to have been pretty serious about coding and building stuff with Arduino! I've been playing with the Particle Photon (which has many similarities with Arduino) and making a few projects, but not as big as yours (not yet at least).

Wanted to make a drawing machine too, but got stuck in building it, not coding it hah... Do you have a post about the rat sculpture? That sounds pretty interesting :) I've also been in situations where the most simple lines of code with the least effort rewarded the most in functionality, while sometimes I'd spend days and days on a complicated code that just didn't want to work as I wanted.

What did the UV light sculpture do?

True. If you ever change your mind though, you should maybe see some videos about the old computers that are still very retro and used for demoshows today (amiga, commodore etc.). And if it seems interesting, assembly language would be great for learning on one of those old computers, it's really really fun and easy :-P I've only managed to make a few sounds and draw some lines on one of them, in BASIC language. Man that was fun! :-D
