ESP by Ralf (Fairmagic) Rudolph

Here is a straight forward effect which is enabled by a clever gimmick. You ask somebody to think of any one of the five ESP symbols. Then you look deep into their eyes, read their mind, and commit by writing what you read in their mind on a little notebook. Then you ask them to reveal their thoughts. You will be able to show that you wrote down the same symbol.

No force. Any one of the five ESP symbols can be selected.
You are not limited to the ESP symbols. Any other small number of symbols, numbers, etc. can be used.
The notepad is gimmicked. It can be shown but not handed out.
A bit of arts and crafts is necessary to make the gimmick.
