Watching Nynan Cat in Terminal is most likely why terminal exists.

All you need to do is:

1. Open your Terminal in Mac OS X or Windows or Linux or whatever the hell you are running your toaster on. 
2. Type telnet miku.acm.uiuc.edu. 
3. Enjoy an endless nyancat loop in glorious ASCII.

Thank you Gizmodo

When I ran it, I had to add another thing:

TERM=ascii telnet miku.acm.uiuc.edu.  

If you don’t know where Terminal is on your Mac, go to Utilities>Terminal.  Then type that up there at the prompt and hit enter!  

It’s fun…try it :)
