did you know about the venetian blinds demo?
activision was formed by ex-atari programmers who were unsatisfied with the company. they quickly started making games for the 2600 much better than atari was putting out. so atari sued claiming they had stolen programming knowledge such as the "venetian blinds" technique (second picture) for having previously worked there. david crane showed up to court with the demo and asked "oh you mean this?"
atari lost the lawsuit
