I like the way you think. :)

Though I think 720p is towards the low end of resolutions this'll work on -- the cimbar code itself is 1024x1024, and while there's some wiggle room (hamming distance between the symbols), in my experience it gets pretty iffy below 900x900.

Also... I should probably update the overlay to auto-hide when a file is selected -- it helps a lot to have the full color range.
