Tom's idea of using the version of the Erdnase (Houdini) change for continuous color changes is interesting. Harvey Rosenthal has also done substantial work on this sleight.
I found Tom's new booklet very interesting. Much of the material reminds me of the work of another magician, one whom I miss very much -- Tommy Wonder.
Tom relates that his trick "Of Dice and Men" had its genesis in the final image he desired. The magician gets a hug after a spectator rolls a die to choose one card from six, which has "Hug" written on it. As he's getting his hug, he "accidently" reveals the backs of the other cards in a stand, which all read "Kill." The concept and Tom's excellent illustrations are fabulous.
Some of the material consists of concepts from Tom's notebooks, but they are not just food for thought; they are a feast.
