Some time back, there was some talk about the Radar Deck.
Here is a great performance by Richard Osterlind 'using' the Radar Deck.

I remember when i first watch him perform this effect i was thinking " NO WAY! That is impossible!!!"
This is one of the closest thing to real mind reading. Just look at the card then i know which card you are looking at.
I wonder if it is as easy to carry out as the way Richard Osterlind did.
A very strong persentation seem to be required for this effect to come across well.
