So that software that I wrote to track red things… now it tracks red laser pointer dots! I have a bit of finessing to do on the look of the lines, but the “system” more or less works. Below is a shot of some laser graffiti I captured by doodling 20 ft away on my back wall.
As an unintended neat side effect, I discovered I can track the blinking red lights of airplanes flying over. 🙂 With a fisheye lens and a higher resolution camera, it might be really neat to show the air traffic corridors as a series of graffiti lines across the sky. More (cooler looking) stuff coming shortly!
