"Circus Linux!" is a clone of the Atari 2600 game "Circus
Atari", produced by Atari, Inc. (which is itself a clone
of an earlier arcade game named, simply "Circus").
The object is to move a teeter-totter back and forth across
the screen to bounce clowns up into the air. When they reach
the top, they pop rows of balloons and then fall back down.
The gameplay is similar to the classics "Breakout" and
"Arkanoid".
