An Easter Egg is a hidden feature or novelty that the programmers have put into their software. It can be an image, sound or movie sequence and are hidden to some degree. Some Easter Eggs can be seen during the course of a game but some are deeply imbedded and may require very specific steps to find them.
If you play the file '\QTW\Channel\holoamth.mov' on the game CD you will see a clip of Achenar muttering gibberish in Channelwood. If the movie is played backwards, Achenar actually says something like, "Rush Limbaugh understands."
This Easter Egg can only be seen in the Jaguar (Atari) version of Myst. To get access to it you have to enter May 22, 1970 6:30AM in the planetarium. The immediate front of the (still functioning) library will now be the Atari building. Click up to see the Atari team that ported Myst to Jaguar.
On January 26, 2001, the hunt for realMyst easter eggs officially began. Spyder, a shadowy figure connected with Cyan, posted the first of many cryptic messages through Cyan Chat. Spyder's statements were episodic and brief, bracketed by a comment on the night's CC attendance and a swift farewell. Among the things that were revealed were some employee photos and their family on the imager in Rime as well as very early concept images from Uru.
