multiple object tracking

[iriggi]

I need to draw red balls that bounce from left to right and a ball which rotates (always the same uniform mouvement, a little circle in the middle). the illusion is that all the balls are bouncing, but it is not true.

The problem is that I don't know how to made a python program who shows that.

I know, thank you, i don't want people doing my program. I just want to know how to do the bouncing from left to right

I know some about Tkinter. You would start with a Tkinter.Canvas widget and create an oval object on the canvas. You can simulate movement by deleting the oval object and creating a new one in a slightly different position repeatedly at short time intervals. I have found the documentation here to be useful.

You could also use something like matplotlib to create the image files (from a graph) and then stitch them together. Or gnuplot.py to run Gnuplot and repeatedly replot.
