While I want an ever larger screen on which to plot my everyday work, this video from the MIT Media LabCAST is a very suggestive take on what many fragmented yet coordinated screens might accomplish. The demonstration strikes me as a visual analog of the Internet itself, presenting countless possibilities, each of which can be called and potentially controlled - or sifted - by the user. In addition to the purely visual element, the technology opens up the possibility of incorporating touch as well, an idea the lab has featured in a separate LabCAST.
So if the medium is the message, how might widespread deployment of this technology change us?
UPDATE: Ethan Zuckerman says Siftables rocked TED.
