The design specifications I set for this pad were numerous. I wanted:
(1) An easily replaced common notepad.
(2) An instant access impression.
(3) Eliminate the necessity of ripping the page from the notepad before drawing on it.
(4) Reset it instantly, even in front of people.
(5) A design innovation so cool that it would delight Mentalists when they saw it (creator’s pride!).

I think the Butterfly meets all the above criteria. I really, really like this thing.

The Effect

-- of course, is one of Information Replication. A person writes down a piece of information: a word, name or drawing, and you reveal it. The Butterfly is the Modus Operandi; your performing skill is the critical element to selling the effect.
