The cheapest I've found it is $39.38 on penguinmagic.com - the list price is $52.50. Every site that offers it lists the same few illusions and then says "many more." Would anyone be able to share a full list of illusions, maybe difficulty level... and perhaps share whether or not the projects they've tried included specific enough directions? Are these illusions the type of thing that can be found elsewhere? Inquiring minds want to know...There is a book out called Haunted Illusions by Paul Osbourne. It's a fantastic book. I've built many of the sets in there. The girl to gorilla is one of my favorites and I've built quite a few of them.
