I found this on Biotek.net but before you try this out you must promise that you are not currently working in the kitchen, have something in the oven or watching the baby. I found it on my lunch break so that doesn’t count.

You will not be able to continue anything else you are doing. *waves hand in an arc in front of your face*

All set? This works in Windows XP (and on Windows Vista too, as reported).

* Go to Start
* Click Run
* Type: Telnet.
* [A DOS window (also known as a command prompt) will appear.]
* In the DOS window type the letter “o” (without the quotes)
* Then type: towel.blinkenlights.nl so that the line looks like this:

Microsoft Telnet> o towel.blinkenlights.nl

* Press Enter

Enjoy the show.
