The image above scans perfectly fine in the program I use, so it almost certainly will scan in any other.
I made this by using the "We accept Bitcoin" text as a selection mask and coloring the light sections a pastel red, and the dark sections a darker red. The theory should work with any other picture we care to put on there, so long as the color differences are about equal. Red, of course, isn't the only color possible, I just picked it for how well it stands out against black.
I'm diggin' it! In the spirit of quilt designs, I think we need to come up with a design/color-scheme for the three corner blocks (all the same).
