Derren's Haunted Pack is excellent, although it isn't entirely original to him as far as my knowledge goes.
Sean is right, I've been working on a handling of an impromptu Haunted Pack for a while, although I have to give credit to my good friend Mikey as the method was something he suggested.
Danny's effect Motion is excellent, although it isn't like traditional Haunted Packs where the cards cut to the selection. It's more of a rising card, where the selected card visually rises out of the deck. It looks fantastic when he performs it, but I find it quite difficult.
I would recommend Derren's version. I've blown people away, as it looks so clean.
