The Equinox Clock is an Arduino based creation that lets you tell time day or night with a rainbow-hued ring of LEDs illuminating your wall. Its hollow circular shape looks a lot like that bladeless fan, the Dyson Air Multiplier.

The Equinox Clock uses an Ardunio Mini Pro hooked up to 12 black circuit boards daisy-chained with Molex picoflex cables and 60 RGB LEDs. A capacitive, touch sensitive wire behind the infinity sign lets the clock rotate through different colors (or be powered down), and the color palette changes depending on the time of day.
