Save the code as "quinemas2010.rb" and run it under an terminal bigger than 80 x 24. You can use cygwin if you're a windows user. You may need to use "aoss" or "padsp" if you're using Un*x. I tested it with ruby 1.8.7p299 and 1.9.2p0.

A screencast for you guys who are lazy:


  • Q. Is this a pseudo-Quine because its output is not strictly equal to the code?
    • A. Yes. This is a Quine generator. Run it as follows. You'll find tmp1.rb is certainly a Quine.
$ ruby quinemas2010.rb 0 > tmp1.rb
$ ruby tmp1.rb 0 > tmp2.rb
$ diff tmp1.rb tmp2.rb
  • Q. What does the command line argument mean?

    • A. A random seed which affects how to snow.
  • Q. How does it animate?

    • A. It just prints each frame with the aid of escape sequence. Because it uses only ANSI escape code, it works on almost all terminal emulator (but not cmd.exe).
  • Q. How does it play a sound?

  1. Dude. you are freaking amazing. I told you that already after I saw your globe. Keep getting fun and creating great stuff. And Marry Quinemas too you too.

  2. Wow. What? With sound? Just... wow. Happy Quinemas.
