Just saw that deadmau5 was streaming himself experimenting in touchdesigner on his twitch. Pretty awesome!
I think there is a dude with that same handle in these very forums somewhere…
@harveymoon, he mentioned on his stream that he knows the Derivative people quite well and that they have done a lot of work for his tours so, it might just be the same person!
I have been helping out on his stream. I am jblatta on Twitch.
