I had some time today to troubleshoot the project. Why no i2c devices showing up on the scanner? I thought there myst be bad connections, so I trimmed off the brass parts of each component and kept checking. I though that I'd try the OLED on it's own. Not working. Hmmm. Let me just double check what pins SDA/SCK are on on the Micro. Pin 2 is SDA, check the route of that connection. I have connected it to SCK. What an idiot. So I destroyed my sculpture to find out that I could have just desoldered and reconnected the pins on the arduino. Sigh. Well, at least I can try again with straighter rods.
