If you want to be amazed, check out Star Castle:<p><a href="http:&#x2F;&#x2F;starcastle2600.blogspot.com&#x2F;p&#x2F;star-castle-2600-story.html" rel="nofollow">http:&#x2F;&#x2F;starcastle2600.blogspot.com&#x2F;p&#x2F;star-castle-2600-story....</a><p>This is a recent (2011) Atari game that renders several concentric rotating circles, each with a gap. It&#x27;s the game that Howard Scott Warshaw (the E.T. guy) decided couldn&#x27;t be done on the 2600. Knowing what I know about the 2600 graphics subsystem, I can see why he came to that conclusion.<p>Of course, Warshaw then Star Castle as inspiration for Yar&#x27;s Revenge. This game was widely considered to be excellent... leading to Warshaw having the credibility to be asked to do E.T.
