Sending graphics from openFrameworks to other applications in real time via Syphon

This is a quick video tutorial I put together to show you how to get graphics out of an openFrameworks project and into another application (in this case Max MSP), using the free application Syphon. Syphon utilizes the IOSurface framework to store graphics on a buffer which can be received by other applications. Here I use an openFrameworks project called ofxSlitscan to manipulate the webcam feed to utilize slitscanning, then pass the slitscanned video on to Max MSP, where I can continue to
