Japanese casual basics chain Beams has released a DVD of video art which is available for free to customers of its Beams T stores. You can check some clips from BTTV here at kurandofuruya's YouTube page. We were caught in particular by this stunning sequence of light sculptures created by Kieph and Aysushi Sasaki. It's a beautifully immaterial, transient form of writing. Thanks to Pink Tentacle for the tip.
