Easter Eggs.

I discovered something new this morning, which my technology savvy colleagues probably already know, my son did, but which I didn't. Apparently, a lot of office software but also computer games and dvd's have something hidden called an Easter egg. The software programmers hide something extra which can only be accessed by pressing certain keys in a particular order.
I thought it was appropriate to mention this as it's Easter Sunday. Here is a link for those interested in reading more about the subject.
