Seeing Around Corners With Dual Photography
Via /. We present a novel photographic technique called dual photography, which exploits Helmholtz reciprocity to interchange the lights and cameras in a scene. With a video projector providing structured illumination, reciprocity permits us to generate pictures from the viewpoint of the projector, even though no camera was present at that location. The technique is completely image-based, requiring no knowledge of scene geometry or surface properties, and by its nature automatically includes all transport paths, including shadows, interreflections and caustics. I need to really read this again and watch the video. Link.
The future of music mixing and sampling is here. It’s going to be around a ping pong table, with headbands…”We were playing ping pong with paddles that had piezo sensors in them. When the paddles hit the ball, they would actuate the starting and ending points of a sample – so the faster we played, the more ‘frantic’ the sonic output. It was a fun piece.” 
This is a pretty neat project from Mauricio Melo (there isn’t a how-to but I think it’ll be easy to replicate) It’s a networked emoticon device. You log onto it through the Internet and let your other significant at home know if something at work or at school has made you happy, sad, so-so, or upset. The devices are connected to the Internet through an Xport controlled by a Microchip that handles the basic communications. A series of switches reciprocally activate four LEDs that light the transparent emoticons. Via 
All the cool kids in the Shire are tagging it up with Moss Graffiti, maybe not- but here’s how to make Moss graffiti. Ingredients: 1 can of beer, 1/2 teaspoon of sugar and several clumps of garden moss. There’s a neat spot in the backyard here, I’m going to try it out and post up pictures. Might make some neat art. 
Maybe we can get the 3D printer guy to hang out with the 3D scanner fellow and we’ll be another step closer to replicators. Here’s a 3D laser scanner using a Quickcam Pro 4000 camera, s100 SMS controller card and LSG 35 geared motor.
