Keith Barry : Brain magic

Keith Barry at TED2004  (transcript)
Brain magic
Summary
Unfortunately, the story doesn't have many pages to read and you can see funny magic.

I'm often deceived by emotional things, for example, when my friends or someone is worried, I think that I have to do something seriously. However, there are situations that they, in fact, have been feeing nothing.

If you can think about something skeptically, you will see through something, so magic is all about directing attention. If you don't want someone to look at your right hand, then you don't look at it, but if you want someone to look at your right hand, then you look at it, too. Thus I don't try to look there where all people see.

The speaker tells us that magic is to deal with psychological and mind-reading effects, thus you have to suppress your feeling and you think skeptically.
I could do like the speaker could take his interlacing hands.
