So you might already know this, but Star Wars Episode IV is implemented in Windows XP, and possibly other Operating Systems, but I haven’t tried on any other.
Anyway just go to Start> Run > and then write:
telnet towel.blinkenlights.nl
Watch Away!
🙂
FYI – No, it’s not a trick. No, it’s not going to shut your computer down. It will actually play Star Wars rendered entirely in text graphics.
