Hi guys! So heres the deal: This year, one of the teachers in my school is going away, and each student has to make a card for him. I thought it would be a neat idea to write self working trick on the back. Any tricks come to mind? I once saw one where you layed out several cards out, have someone pick a card, and then give some instructions (go to the nearest suit card on your right, etc). If you know what this trick is called, or of any other trick that i could use, please let me know. Thanks in advance.
