No numbers, no hands, no way of even telling the time.
Until, that is, you step up to interact with it.
A plywood ring conceals 12 LEDs and sensors connected to an Arduino, an open-source, sensor-driven electronics platform, which turns off all but three of the LEDs when it detects your finger.
Your finger casts shadows from the three LEDs that remain on to create the traditional clock “hands” that we are used to.
The hour and minute “hands” are much darker than the faint shadow of the second “hand” to minimise confusion in what the time is.
Now, if only they could make that power cord a bit more discrete I’d definitely be looking to get one!
