Jonathan,

Thank you. I was working on a simple camera calibration and needed a good target. Your random colored grid made a great clear image. Correcting the camera colors, positions and intensities is much easier with a quantitative reference. The only suggestion I have is to also have the Javascript version. There are about 4.8 Billion people with some access to the Internet, and they all use browsers and systems that have some access to Javascript. But C requires a considerable investment in finding, learning and sharing. It does not need to be that hard (standardizing C methods of sharing for global communities of billions of people) but not without effort.

Thank you,
