Easter eggs

Since windows was invented, programers and developers found a way to comunicate messages in hidden parts of their sofware, I remember when I was around 12 or 13 years old , somebody told me about this hidden messages. I was so curious and I decided to check it out.

I was surprissed when I introduced the " secret code" and lots of pictures pop up in my screen , images of the programers and even Bill Gates apeared.

Some people think that this is bad , or maybe they think about subliminal messages, but maybe it is a way to show their work to the users and get some credit.
