Grid multiple movies into 1 window - examplepatch?

And the answer is to see tutorial 13, use jit.glue, jit.scissors and move on to rendering multiple videoplanes in an opengl window.

However, I am not set on whether I want to use a 2x2, 3x3 or 4x4 matrix, therefore I would like to know if anyone has come up with a flexible solution. Eg. a lists choosing between 2x2 - 4x4 arguments for the video output, and some easy way to read the videos.
