Strange, strange. iPython is apparently having some effect here: I tried
ipython -pylab animation.py
and I got a figure with the initial plot, but nothing further
happened. After closing the plot, I typed
run animation.py
at the ipython prompt, and saw the initial plot, erasure, and
animation that I expected. Can you try running with a plain
python animation.py
I've attached a new version of the script with some changes suggested
offline by Ryan May - he was seeing platform or wx-specific behavior
related to event handling. All bugs remaining are mine

I've attached a somewhat unpolished but functional example that shows
time-synchronized animation of multiple scatter plots. It uses the wx
backend explicitly, due to some issues with the idle event handling.
The collection returned by scatter() lacks anything akin to a set_data
method.
Yup, you want this instead:
collection.set_offsets(xy)
collection.set_array(s)

indeed it works with python now, provided I uncomment the wxAgg setting in the script.
best,
