The backstory to this game is very interesting- I'll try to sum it up as best I can...
Activision was the first third-party games publisher in the world, putting out games made by all different developers on the Atari 2600. The company was founded mostly by ex-Atari employees.
One of those men was Bob Whitehead, an ex-Atari programmer who came up with a very important programming technique he called "venetian blinds". What it did was make it possible to show 8 sprites in a row on the old Atari, while it was famously limited to usually only show 6 at a time. So it was a great new way to get around one of the system's major flaws.
However; when Bob formed Activision, he took the technique with him and used it in several new games. Atari claimed that venetian blinds was something they owned, and Bob had STOLEN it.
When Atari's lawyers questioned him about the situation, Bob sent over THIS demo, Venetian Blinds, as a joke. Atari didn't find it so funny and went on to sue the shit out of Activision.
But in the end they lost, because it was a dumb case to begin with.
