All magic is in inclined cut, areas slightly changed, there is puzzle with triangle shapes on Wikipedia

7x9=63 or 64 or 65 or 66. It's that simple.

Does anybody knows what the name is off this puzzle?

Flipped the piece

why do you think that everything is illusion?? this is simple geometry. after he starts to take out squares, there is gap in between.

Watch the hand on the right at 0:45 he flips the piece over.
