So there's a long story to this. For the past 3 or so years, I've done this volunteer magic thing where I teach some basic card tricks and games to poor children. It's really fun. Anyway, it turns out that one of the owners of the yogurt shop I work at was part of the organization that does this massive charity event each year. She asked if I could do magic while Santa visited the yogurt shop. I did magic for the kids who came in and even showed the owners and Santa himself some tricks in the slow parts. Santa was actually the other owner's dad (the store is owned by two families) and he asked if I'd do some walk around magic at this party thing he's having. His son, the owner suggested I design some business cards and even said he'd pay for the first 100 for me, which was nice of him. I just have to send him a design. Now I've seen magician cards that react with heat to reveal the message or work as a magic trick themselves. I can't do something like this as many seem expensive to make and cumbersome. I know what important information I need to include and that it should be clear and concise on the front of the card, but I need ideas to make the design creative and unique. I was thinking I'd leave the back blank to use as a billet but I've also been toying with including a hidden card reveal or something within the design. I don't want it to look cheesy though. I've also been thinking of cool ways to present the cards, besides using them as billets for other tricks. I've seen people pull them from a fire wallet when people ask for a business card. I've also seen the idea of running one through your hand to "print" it. There's also an app that makes it look like the card prints into your phone and then you pull it from your phone, if that makes sense. It's made by the same people as Card2Phone so if you know what that is, it should make sense. Also, any advice for this type of walk around magic? I feel like I have a pretty good idea what to do but it's always nice to get tips from the more seasoned professionals. Just any advice at all will be welcome: dos and don'ts, pocket management, audience management (a lot of them will be drunk apparently), suggestions for effects, etc. Tl;dr, I need ideas for a magic business card design as well as ways to produce or present the cards, as well as tips for performing at the party thing. Thanks guys!
