just imagine how much time went into building the 1st effect.
Its simple in theory but in execution would be extremely difficult. I don't know how magical the effect would play to the audience though. The manipulation is definitely way beyond most but it screams gimmicked board to me.
I just watched the video again, and there is a lot of clapping but not a lot of gasps.
Clearly the board was gimmicked to change colors, but the sleights used for the ball manipulation were pretty impressive.
