Little game I made to entertain my one year old on a spare laptop

colours.py

#!/usr/bin env python

import pygame
from random import randint

d = pygame.display.set_mode( (800, 600) )
pygame.display.toggle_fullscreen()

def rnd_bg():
    d.fill(((randint(0, 255), randint(0, 255), randint(0, 255), 255)))
    pygame.display.flip()

while 1:
    e = pygame.event.wait()

    if e.type == pygame.KEYDOWN:
        rnd_bg()
    elif e.type == pygame.QUIT:
        break
                                          
    elif e.type == pygame.MOUSEMOTION:
        c = ((randint(0, 255), randint(0, 255), randint(0, 255), 255))
        pygame.draw.circle(d, c, e.pos, abs(e.rel[0]))
        pygame.display.flip()
        pygame.time.wait(20)
