This is a terrific little effect. People will probably accuse you of moving the letters around with
your fingers or something - until they touch the case and realize that's impossible. Then they'll
just be amazed. Seriously, this one has it all - it's relatively easy, can be played for laughs,
can be incorporated into a nice storyline, and has a very visual magic payoff at the end. I'm going
to pick up a couple of extra just in case they ever stop making these.
