This Sticky Light demonstration looks like tons of fun! It was created by Alvaro Cassinelli, Kuribara Yusaku and Stephane Perrin of the Department of Information Physics and Computing at the Ishikawa Komuro Laboratory of the university of Tokyo.

"As an art installation, the most interesting aspect of the work is that it promotes a reflection on the role of light as a passive substance used for contemplating a painting or a drawing. Natural light, or an artificial spot of light is always necessary to illuminate what we want to see; the quality of the light, the position and angle will modify the perception of a painting. In fact, the source of light is not really passive: it interacts and modifies the perceived work in an essential way. The installation amplifies such effect: it gives the light spot new ways of interacting with the painting; it augments its content by scanning the drawing, following the lines and bouncing on the colors. By moving on the drawing, the light spot attracts the attention of the viewer. It actually forces our sight to follow the dynamic path taken by the light."

Coolest. Thing. EVAR. I’ll take 3.

Anybody know how it works? I figure it would use some kind of camera to read the laser’s 2D “environment.” I think I also saw a video of the laser doing finger tracking in 3D space.

How it works is in the linked article, it uses a single photosensor to measure light levels at the point of the dots and changes the movement of the dots based on if the laser hits something light or dark.

Can someone explain how they use a photodetector and NOT a camera? I can see if there were one PD for each laser, then just use a lens to see if the “next” move would be onto a darker surface. Is this the solution?

would be a great cat toy!
