Video painting is an intriguing art form that utilizes technology, photography, video, and performance art. I have always been a fan of works like these due to their transient nature and surrealist elements. Beyond the shear beauty that comes out of it, the copyright implications are also fascinating. On the one hand there is the copyright in the performance art itself as it is being recorded, but there are also the rights to the pictures, videos, accompanying music, art and design elements, and possibly the code written for the software. Just another good reason to make sure you know who owns what, and which elements you may need to license.

From the creators of the work:
"Video painting is a technology the duo developed that allows them to create the illusion that they are painting videos onto walls with electronic paint rollers they built. It works through custom software that they wrote that tracks the position of the paint rollers and projects video wherever they choose to paint, allowing them to explore the relationship between video, mark making and architecture and create live video collages in real time."
