Hermetic Press has just announced that they are taking pre-orders for Barrie Richardson's "Act Two"! This is the sequel to his now-classic Theater of the Mind.
Any reader of this blog should read the original, especially the "Mental Gymnastics" chapter, which is full of great and original lightning calculation and memory feats. As a matter of fact, the write-up for Act Two promises (among other things):
Various feats of superhuman memory and rapid calculation convince audiences of the performer's extraordinary mental powers—and their own.
There are also many other interesting goodies promised, and if his previous book is any indication, this book is probably worth the wait. I'll be reviewing this as soon as I get a chance to go through my own copy.
