A large part of my work is writing about and sharing the Vuo story. We believe there are all kinds of people who will embrace Vuo once they discover it’s out there. So, my efforts include helping create the Vuo website, writing press releases, submitting conference proposals and generally figuring out how to create excitement and how to spread the word about Vuo. I occasionally help out with Vuo e-mail support and I'm part of the think-tank called "Team Vuo."
Glad your issue is solved. As the node documentation mentions, to mimic the way the Shadertoy website handles interaction, Mouse is Pressed input needs to be provided. Receive Mouse Moves only fires an event when the mouse is moved, not with every display refresh.
