Another option would be to just use the scene.rect function for every pixel. Performance will probably not be good enough that you can actually draw a rectangle for every pixel on the screen (especially on a retina screen), but you could use larger squares to get a pixellated look, or just draw within a smaller area.

the first method is good but I don t understand how create a simple animation. Any simple example?

You could create multiple frames in an animated gif https://forum.omz-software.com/topic/2052/gif-art-in-python

yes this a work around, i would like to have a minimun of interation with what i draw... Using the first solution it' s impossible to draw it on screen ?

Try @omz's suggestion. That lets you draw directly to the screen.
