Following will teach you how to play the "easter-egg" (which actually isn't, but many people describe this as an easter egg) of ASCII-Art Star Wars (or Star Wars in terminal/telnet, whatever), the one you normally starts like this:
$ telnet towel.blinkenlights.nl- Before you start, ensure Node.js is installed.
- Navigate to www.asciimation.co.nz, the original home of that ASCII-Art Star Wars.
- Press F12 to open developer tools.
