I used this on a raspberry pi for this kinetic sculpture: https://www.youtube.com/watch?v=6xAiKI6XswM
I was thankful that it worked on a variety of diverse faces, even masked somewhat.
That's pretty neat, how does it look like from the viewer's perspective?
Also what's the mechanism behind the turning? If I counted this right it would have to be like 48 servos which sounds expensive, but also is an interesting number because that's exactly 3 of those PCA 16 channel servo expansion boards...
