Hey there!
Could you help me with something that is driving me mad? I've seen this trick before in a magic shop but now I can't remember its name.
Effect: A dvd is shown completely blank (its box and its face is white, nothing written on it) then you ask your spectactor to sign that part that it's faced down when you put a dvd in the dvd drive. You show your spectator a pack of cinema tickets with various films you've watched over the years and you tell them to pick one out. When you re-open the box (which is still without any labels on it) the signed dvd is the original dvd of the chosen film. When you close the box, there is the label of the same film.
Hope you understand my description.

Thanks a lot!
