I find it oddly reassuring that this little gem still inhabits the Internet.
Open up your favorite telnet client and connect to towel.blinkenlights.nl
If you’re using Windows just click Start, Run and type cmd to open a command prompt. Then type telnet towel.blinkenlights.nl and then hit enter.
If you’re using Mac OS X or later you can open up the Terminal application found in the Utilities folder under Applications and then type telnet towel.blinkenlights.nl and then hit enter.
