For the ultimate product of nerd and fan-boy, all’s you gotta do is:
(Note – Windows machines only)

1. Start Menu
2. Run Command
3. Copy telnet towel.blinkenlights.nl in the box, and hit Enter.

An MS-DOS window will pop open and from there, all you have to do is watch.

I feel happy that there really are people who are nerdier than I could ever be.

Alternatively, you hold down the windows key and press R. That will give you the run box. Paste the bold text into the run box and hit enter and away you go.

I can’t even begin to imagine how much time and effort this took. Absolutely gorgeous.
