You may have noticed the picture of Mario on the frontpage. The picture was taken a few years ago. It was the door to the office I shared with a few fellow students.
You may also have noticed what happens when you click on the picture. A sound is played - a man saying "it's- it's- it's a series of tubes!" If you've been visiting the site from multiple devices you should have heard the sound from all of the devices!
One day I was thinking: "Hm, Mario is a plumber. A plumber fixes the tubes. The internet is a series of tubes!"
