  $2000-$3fff was made for the Ludum Dare
  #31 Game Jam in December 2014. It is
  actually more than just a game. Some of
  you will say it's crap, but we would
  point out that it's both a game and a
  piece of art. The idea and concept is
  actually great:

  This is the official description of the
  game:

  "$2000-$3fff is a Commodore 64 program
  which displays its entire memory on the
  screen, then draws missiles into it.

  Use a joystick in port 1 to target your
  dangerous explosive weapon. If you
  don't have a C64 handy, feel free to
  use an emulator like VICE.
