Tina (2018-10-29)

Dot graphics.

Tina draws an animated sprite to the console.  Use arrow keys or
VI keys to change direction, type 'q' or Ctrl+C to exit.

Requires Ruby and a terminal that supports 8bit color palette, which
includes the usual xterm variants (xterm, xfce4-terminal,
gnome-terminal, putty, mintty, etc).  Note that you might need to set
"TERM=xterm-256color" if you are running this inside screen or tmux.
Does not work with Windows cmd.exe due to lack of 8bit color palette.

If your terminal has square fonts instead of fonts with aspect ratio
of 1:2, change "!!" on line 40 to "! ".

Based on Tina Branford from Final Fantasy VI.
