A simple device you place under your TV to recreate the viewscreen lights seen under the main screen in Star Trek. Powered by USB, which all TVs have these days. It could emit Sound Effects like the pings heard on the show.
Thinkgeek kicked the tires on this one, but I don’t think they’ll be making it.
Flatscreen TV’s are an amazing space-saver. So why don’t other electronics follow suit? With the same flat orientation of the TV applied to other electronics (like DVD players, stereos, and game systems), you could have an entertainment unit as deep as 6 inches, or about the width of a DVD case.
Sure you might have to fasten things down to keep everything firmly in place, but it’s a small price to pay to gain additional room. The reclaimed real estate would be beneficial to those living in a smaller space.
As for the component electronics themselves, a few design changes would be needed, like the DVD slot (see above). and a way to conceal the wires (something like this flat PS4 concept).
