This isn't a trick but it is a fantastic concept.
The best way to describe it is you know how
if you type 58008 into a calculator and turn it upside down it looks like a word, well it's that
concept but applied to revealations for a trick.
This concept won't work equally as well
with every letter, but it's up to you to design a routine where the outcome is the most clear. This
may not make sense at the moment but when you get it it will!
