Lichtfaktor

Since Leah posted her light writing piece I think she (and all of you) will be interested in the work of Lichtfaktor which are a couple of very active German artists. But in this video (no need to speak German to understand it!) you can also see the work of my favorite light graffiti collective. The fabulous and radical (and OPEN SOURCE!!! yeah!) Graffiti Research Lab. There is also a piece on the AR (augmented reality) group DAIM using tracking fiducials to create 3 dimensional light graffiti. This is the 21st century after all...
