Here's some Renci Vid from SC08, showing some of the technology in the Renci booth. As stated before, I'd love to put a touch table in as a centerpiece to the Social Computing Room, and have multi-touch applications that interact with the 360-degree viz display. This idea meshes well with the ideas demonstrated by InfoMesa.
Also cool to note is the HoloPanel that can be seen in the corner of the booth. A pair of these was used in the Social Computing Room as a part of the Spectacular Justice installation, and they were stunning!
All that said, really this is just to share some cool technology. I'm lucky to work with such smart and resourceful people at Renci.
