I hacked the capacitive touch SAO penguins to add obvious missing stuff :)

The 2nd board, I couldn't help but put a hole in it and install SPI screens:

started with one screen

then got the 2 original I2C screens to display blinking eyes and worked on the SPI screen

SPI is a bus that allows multiple devices, so I added 2 screens

getting the Arduino_GFX lib to support both screens was a bit challenging, but got it working

And here is the last result with everything working and running 5 different demos on 4 screens:

This video has the badge I built for that conference, but never got to wear:
