I never got around to cleaning up my initial SSMU app code and posting it to my GitHub. Shortly after I started working on a app that could render shapes requested by an Intel Galileo board over WiFi. It started with the same base code as the original SSMU app and was able to reuse the same communication protocol as well. 

Now I'll be able to fully merge the changes from the original SSMU and the WiFiScreen code since the goal is to have both wired and wireless communication. As a bonus, since my previous code was developed for the Intel Galileo board, it will be easy to port the relevant portions to a BeagleBone Black or Raspberry Pi. This way the smaller single-board computer can act as a hub and translate the nRF24L01+ payloads to WiFi ones. 

Leveraging these common devices means that I don't need to increase the SSMU BOM just to include a WiFi radio and can instead use the much cheaper (~$1) nRF module.
