Ah the sweet stench of success. In This Case, it's a magic demo video. First off, I don't get the products name in relation to the effect. Must be a limey thing. Secondly, the video edits out VERY important details. At least Richard Sanders had the Canadian bacon bits to do a full take of his Interlace effect.
So, being the magical demo video watchdog I am, I say for shame. I also say for shame as I have been doing this same effect for years and don't have to go to my pockets to make the trick work.
Carl Cloutier is rolling over in his grave... even tho' he's not dead.
He's prolly just rolling over in his bed.
