You are of course correct Richard, so going back on topic, Richard Busch has a flair for thinking out the psychology behind his presentation as well as the technical. Besides his soon to be a mentalism classic (Peek Performances), the world's authority on Peeks also has several other excellent works out there.
"Number...Please?" is a brilliant work on number effects and elevates them far above the usual take a number, reverse it, add, subtract and take ther square root..... I cannot recommend this enough for magicians as well as Mentalists. Even if you do not use the specific effects, you WILL use the thinking behind them for other applications.
""Mind Over Number" is also a brilliant stand alone effect that he sells and it too is brilliant. The beginning of January will also see the release of the best version of a Peek Wallet to come out in years by Richard Busch. Keep an eye out for it.
Since I am also the business partner of Richard I will also offer anyone that has not got both "Peek Performances" and "Number...Please?", a special offer of $75 + shipping for both together from our on-line store, Ab StageCraft - http://www.stores.ebay.ca/ABstagecraft
