Hi,
I would have liked instructions on how to link the balls. Do you just draw between the balls or have to select one as a starting point? Sometimes they were yellow and sometimes green. I can see single and double links forming but didn't understand how I was doing them.
When the structure first appears it seems to already have some links drawn in which confused me?
The hand tracking is a nice idea but (maybe it's just me) my hands naturally make the shape that moves the structure unintentionally. It would be good it the structure stayed in place so I could walk around it.
