Nifty, thanks for sharing!

Looks like you were using a coprocessor and Grip? What sort of coprocessor was it, and how did you like working with it?

Looks like it was a TK1 or TX1. Either would be faster than a Pi, even without GPU support.

We used a Pi2...unfortunately we didn't get it working as well as we wanted. Grip offseason updates look promising though!

Gotcha, cool stuff! Thanks!
