Sorry for the delay everyone...the winners I chose never responded to their private messages. I apologize that the new winners had to wait so long for this to come to a conclusion.
New winners:
mowcius
Submitted several project ideas, any of which will work with the Centipede Shield. Leans a bit toward the output-only side of things, but I think mowcius will find some good uses.
kokuma
The musical instrument idea looks really interesting, and could require a lot of inputs and outputs. Definitely looking forward to seeing what this project looks like!
I am sending PMs to the two new winners to request shipping information.
