I think we should make it whoever can come up with the best story for what they're going to do with said 'magic items'. Just another idea to throw into the pot I guess...
I think if he wants to sell them, he will sell them. If he wants to give them away, he will give them away. If he wants to blow them up with firecrackers, he will do that (hey, there's an idea)
Anyways. Depends on how many items, I would trow different kind of contest for each item. And I would make it that noone can win two contests. Se that everybody has a chance.
i think people should post a video of a performance, but with at least an actual spectator, and an actual reaction. As opposed to a blurry youtube video, playing linkin park with a magician doing a poorly perfomed pass, how about a real live performance with real life misdirection, etc...
i think there should be like a random selection using this forum, you have an impartial person pick a number between 1 and however many posts this reaches and then... go to that post and waalaaahh you have a winner and that individual win ONE effect, you go through one at a time if there arent enough posts to meet the number of efects you are giving away then do the math and depending upon however many effects ther are divided by number of posts you give that many per winner
