Sprite strip animator demo
 
Requires spritesheet.spritesheet and the Explode1.bmp through Explode5.bmp
found in the sprite pack at
http://lostgarden.com/2005/03/download-complete-set-of-sweet-8-bit.html
 
I had to make the following addition to method spritesheet.image_at in
order to provide the means to handle sprite strip cells with borders:
 
            elif type(colorkey) not in (pygame.Color,tuple,list):
                colorkey = image.get_at((colorkey,colorkey))
