mustacheme

#!/bin/sh
#
# mustacheme 
#   expanded from an idea from Rick Olson (@technoweenie)
#
# Takes a .gif, splits it into constituent frames, mustaches each, restitches
# the gif, and uploads to cloudapp.
#
# This leverages the nifty service mustachify.me, which will analyze your photo,
# identify faces, and add a mustache to your image.
#
# If the .gif is a remote file, we'll download it and blow it up locally.
#
#   $1 - the path of the gif
#
# Examples:
#
#   mustacheme holman-jumping-off-cliff-into-butter.gif
#   mustacheme http://github.com/holman/butter/blob/master/holman-butter.gif
#
# Dependencies:
#
#   - ImageMagick. If you're on a Mac, run:
#       brew install imagemagick
#   - wget
#   - cloudapp: https://github.com/holman/dotfiles/blob/master/bin/cloudapp
#   - gifme:    https://github.com/holman/gifme
