I found this code via Public Lab’s Thermal Photography project. Growpoodle is basically the free and open source equivalent of glowdoodle which allows you to ‘paint with light’.
I wanted to run the FOSS version but it was not working because it had not been updated in a while, so I fixed it and it is now merged with the main growpoodle repository; works on Gnu/Linux, Mac and Windows operating systems, Enjoy! ^-^
