For a class I am going to teach I would like students to get a
good feeling for the time-dependence of some p.d.e. So I am 
looking for a public domain graphics software which allows
to do simple animation: draw lines, erase them and redraw them
slightly changed. 

On my own machine I use PHIGS double buffering
for that, but  I have to implement it on another machine which runs
X-windows.

Can anybody point me to a solution which is better than redrawing
the figure in gnuplot which gives a very flickery `movie'?

Thank you
