There's only so much Sony could show off at the world's biggest consumer electronics show. According to the video embedded below, the company's looking to tie together all of your (presumably Sony-branded) screens with a single "Dot Switch". On the concept demo, a pair of ethereal arms are able to control music, TV, lights and a confetti shower through what appears to be an Sony Ericsson Xperia Arc. The company's keeping pretty vague on the technicalities of it all at this point, but it looks like it would forgo the typical infra-red communication seen on other devices. Expect to hear more on this in just over a month away. Until then, let the delicate chiploops of this teaser ameliorate that post-CES come-down.
