I've made a little proof-of-concept from the timer interact widget and
this -- I think it's pretty awesome:
1) apply http://sage.math.washington.edu/home/boothby/timer.patch
2) upload jquery.flot_r135.js into the data directory of a worksheet
3) paste the attached into a worksheet (in edit mode)
4) Press "start"
Currently, changing more than one @interact widget at a time
"forgets", everything but the first. So, to play with the slider while
the timer is running, you might have to change the "t=timer(1000)" in
the @interact to "t=timer(2000)" or bigger, depending on processor
speed / network latency.
