Excellent, this is more or less exactly what I was looking to do.  Just
for the sake of clarity I think there were a few errors in the below
that I'll correct for everyone's benefit:

I think you meant event.type and not just plain event.

After the screensaver returns you should update last_event_time or else
it'll go right back into screensaver mode.

Again I think you meant event.type

Terrific effects indeed.

Much thanks for the sample, this certainly pointed me in the right
direction (er, more like carried me down the road on your back :)
Thanks again.
