# pnginator.rb: pack a .js file into a PNG image with an HTML payload;
# when saved with an .html extension and opened in a browser, the HTML extracts and executes
# the javascript.
# Usage: ruby pnginator.rb input.js output.png.html
# By Gasman <>
# from an original idea by Daeken:
# Encode inputfile.tar.gz as a series of video frames
# Frames are written to frames/frameNNNN.png
