So I should just call it each time from the main loop?

I thought it was waiting for a keypress - was wrong.

Actually I do plan to have a different picture for each sprite. So I was 
planning to use the Sprite class to store the pictures and coordinates, and 
only do the blit in the main loop.

As for moving position by speed - I would somehow need to coordinate it with 
real time as "speed per loop" seems somewhat meaningless.

I am a total beginner in pygame and that's why I hoped to see an example. 
Right now I am not even sure how the main loop should be constructed. 

(I really am only doing it because I have a kid unedr 3 yo, and all the 
Linux "games for small children" rely on the mouse - which my kid does not 
grok, and I see his point, the mouse thing is really way less "natural" than 
keys. My aim is to do enough for my son's fun - then I'll just release the 
code, perhaps someone else will want it).
