This is an application i made during the Max MSP course at Designskolen Kolding. It works on mac computers with cameras.
The idea is that you have a computer, a table and three pieces of black
paper. You position the three pieces of paper and the computer on the table, and make the application recognize them by showing it where they are. And you play.
This is usually helpfull when you are waiting for the illustrator or photoshop or some render to finish and you just want to have fun while you wait. There are some limitations howerer, because the build-in camera has only 15 frames per second - you can't really play anything beyond 140bpm. For everybody that wants to play with it a bit more here is the source patcher.
Boring legal stuff: You can download, distribute, share, redistribute, get angry with it and all that stuff as much as you want, as long as i keep the moral rights (that means i am the author). You cannot sell the application, it should be free! And I am not in anyway resposible for something that happens to you, your computer, table or pieces of paper as a result of my application.
