Sonnance Freewheeler: Continuing the simple-but-perfect theme, the Sonnance Freewheeler is a wireless speaker disc, about the size of a car's wheel and able to run for about 8 hours on a full charge. It's also $21,000, but that neither here nor there, "here" being "within the range of you to buy" and "there" being "at all worth it, even if it was." But, pretty!
