I\'ve built these 3 applications. Each of them collects data from user input and creates a csv file. 2 of them rely on the LEAP motion controller. I am trying to figure out
Take a look at http://www.onar3d.com/mother/ It is a library for VJs combine a bunch of little sketches into a performance. You will have to add some code to each of your sketches in order for them to talk and you'll need to write a short sketch to sequence the sketches.
All of the apps will live inside of one processing sketch, so you won't have one app and window close and then the next one open, it will all be one seamless experience. If that is less desirable then @krowe's solution is simple and reliable.
