I'd like to work on a new performance act of walk around mentalism. Can anyone please recommend any good DVDs that I should consider that focus on strong mentalism effects that utilise common items (e.g. post it notes, bits of paper, pens, watches, etc etc) rather than 'props' or items that can't easily be carried in the pockets. I'm looking for material that resets, is portable, and practical. I'd like the effects to look (almost) spontaneous (i.e. no clipboards, blindfolds, slates etc etc)

I already own the Osterlind Mind mysteries set and think they contain some wonderful effects, containing much material that is of the sort that I am looking for. What else should I consider?

Osterlind also has Easy to Master Mental series. Its also a pot of solid gold. Especially check the Al Mann routine on vol 4. I am so angry at Osterlind for revealing this effect. Its called Acidus Novus and has quite a history behind it.
Incidentally there is also a video out called Walk Around Mentalism. I particularly loved one effect using PW.

Some stuff from the max maven videos might do the trick

I suggest getting the osterlind dvds.
max maven stuff is pretty good 2.
its just which one you prefer.

I believe Mark Strivings has a book and video entitled WAM...Walk Around Mentalism.
