Random pixel effect using Max objects... simpler and faster to create in Jitter?

I'm very new to Jitter so would like to sound this idea off to see if anyone can point me in the right direction.

I want to light up a single random pixel in a matrix, and then have that pixel fade to black/transparency over the course of 2000ms. I want this to be happening once every 250ms, so that new pixels are appearing as the older ones fade out.

Using my current knowledge, here's how I would do it. Most of the process is being handled by basic Max objects.

I'm guessing there are simpler and faster ways of generating this kind of effect using Jitter. Can anyone give me a few pointers? Some object suggestions or links to tutorials would be great. Thanks :)
