I dunno if it's just me but... it's not even very good? I feel like magic has moved on from this sort of trick now - people want to be able to see everything that's going on and try to work it out, all the great modern tricks give you full view and use misdirection so you're like "OK wtf". These "curtain" style tricks are a bit old hat... everyone is aware that something is going on "behind the curtain" so it's not really surprising or magical .
