Seems to run stable for hours!
If you can't see your cursor after killing it, run
tput cnorm
Sometimes you may see a seq error if you run it multiple times with different resolutions in the same session. Easier to make a new session, or you can change it unset the variables used initially.
# Play a gif in the terminal indefinitely. Specify the file/url and the horizontal resolution
# Requires the amazing ImageMagick. `(brew|apt-get|yum) install imagemagick`
