The first show of Derren's that I saw was when I was about 15. During MY younger years my father had amazed me with simple magic tricks which, as a kid, I saw as amazing. What Derren did, however, was far more extraordinary. The episode was "Trick of the Mind" Episode 1. The fact that Derren could make a taxi driver who knew London well forget where the London Eye, a prodominant (ugly) feature of the landscape, was was simly incredible. The man has made himself into an artist, and, from what I've seen, a very accomplished one. I have read his book and watched all of his shows, and needless to say I do idolise him somewhat!
If you haven't seen any of his work, I encourage you to do so as soon as you have finished reading this!
