"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.")
