Well, there's this. Not an example of mentalism, but a card trick from earlier in his career. Everything in it is basically sleight of hand and misdirection, but there are so many different techniques in there, strung together with such precision, that it would be extremely difficult to replicate without a huge amount of training.

I don't know if this is the kind of thing Desrtopa was talking about.

I no longer have the book for reference to recall any of the exact techniques, but the author developed an original trick for an international magic competition involved not only misdirection techniques, but original math developed in collaboration with a statistician, and the manual precision to perfectly shuffle a deck repeatedly so that it retains its original order after four shuffles.
