Tech Crunch posted a list of Easter eggs - little hidden software treasures you have to search for inside a program to find. It's a good list, and has a few that I had forgotten about. Among those is what some say is the original software Easter egg (I beg to differ, it might be the first video game Easter egg - but we can save that for another day), from way back in 1979 in the Atari Adventure game (wow, I remember playing that one when it was new!).

Of course, Easter eggs aren't limited to software. DVDs have become a popular place to hide fun little things, too. The Lost DVDs are a good example of discs that have extra stuff you have to poke around to find. Web sites are also often sources of Easter egg fun, and http://www.eeggs.com/ is a good site to find out how to find the in a wide variety of places.

There are nine others in the TechCrunch list, plus a couple more scattered around in the (off-topic) comments. Check it out over at TechCrunch.com.
