# Simple game which can keep small children happy :-)
#
# Bounces images round the screen, rotating, scaling etc. Left clicking
# makes a beep and adds an image, right clicking removes. Nice and simple
# game for small kids :)
#
# Provides a basis for simple games.
#
# Left mouse button - Add an image
# Right mouse button - Remove an image (if over an image, that image)
# Middle mouse button - freeze/unfreeze a moving image if over an image
# Key "P" - Freeze (Pause) all images. (Can still add new moving images)
# Key "U" - Unfreeze (Unpause) all images.
# Key "T" - Pause all moving things, unpause all not moving things (toggle)
# Key "Q" - Quit
