You can run this by telnetting to miku.acm.uiuc.edu.

  telnet miku.acm.uiuc.edu

Ctrl+] = escape.

Website does not open for me. I found this on github: https://github.com/klange/nyancat

But I'm not 100% it's the same thing (github username and this URL seem to match).

It is identical to the URL given on the submitted page before it crumbled from the load.

For anyone else who's unaware of what a "nyan cat" is: http://en.wikipedia.org/wiki/Nyan_Cat

This looks like a good place for my animated terminal nyancat: https://github.com/moshen/Image-Term256Color

Version that doesn't require any cpan modules: https://gist.github.com/1417991

Interestingly enough, it stills looks nice with the Solarized color scheme (on iTerm 2)

I have the solarized color scheme on iTerm 2 and I think it looks terrible. It doesn't look as bright and colorful as the screenshots in the github repo or the actual nyan cat.

That's terrible! :-) He could make a high-fidelity version that uses xterm256 colors 32..255, at least those are independent of the color scheme. There are some negligible differences between different terminal emulators, but close enough...

My 256 color version: https://gist.github.com/1417991

This is awesome. Do you have the source code public anywhere?

The first sentence on the page, right at the top there, gives a GitHub link.

Nyan cat Rspec formatter makes your command line builds more exciting. Watch here: http://vimeo.com/32424001

arggg... they removed telnet in windows 7.

No they didn't. Go to the "Turn Windows features on or off" control panel and check off "Telnet Client".

Huh, so why did HN let you submit this with the same url?
