Bristol-based visual artist Joanie Lemercier has been experimenting with light projected onto 3D canvases. This lastest work created for a Birmingham gallery space was created using sheets of A4 paper folded into pyramids onto which he projected light resulting in an interesting organic effect. No video unfortunately, but you can learn more about his work here.
Update: For a similar project check out this geometric photobooth by Method.
