This animation tool can now control servos using socket.io and Johnny-Five and it’s actually quite fun!  But it is far from production ready. I created a repo for the project: https://github.com/Traverso/go-johnny-go and I have already added a bunch of issues https://github.com/Traverso/go-johnny-go/issues. Nothing major, mostly debris from a rushed prof-of-concept coding spree.
