I was under the impression online communities such as this one were to allow magicians to collaborate in order to succeed. Guess I was wrong... Not that I'm surprised, since I'm a piece of work.
The point of gimmicks such as Smoke and Dresscode are to use your imagination. But I surrender, here's some ideas:
If you like Angle Zero, have a custom shirt designed with the torn corner on it. Keep your jacket/shirt zipped up/buttoned. Open it up once you make the corner vanish, then do Dresscode and patter on, saying it's really appeared (insert place here).
To be honest, the best ideas with the thing come once you have a set routine down. Ideas for it don't help much if they're not in context, and since you haven't provided one, the point is a little lost.
