Thought I'd post a video showing two sniff programs controlling the Flotilla matrix display. In the first the joystick module is used to adjust the position of a single displayed pixel, and the second which I call Matrix Workout several routines are strung together to put it through its paces in an endless loop.
This is working with a matrix software module being developed for Sniff by Ian Stephenson, which should be added to the next release of Sniff.
