See Through Clock Projects the Time
Here’s another cool clock design from Japan’s I.D.E.A. International. This one lets you project a functional analog clock face onto any wall.
The projection clock is housed in a see-through acrylic shell which shows off the unique optics and mechanical components that generate the clock image.
The projector works from up to 13-feet away to produce a clock face around 5-feet in diameter. It should be plenty bright thanks to its 50-watt halogen light source. The I.D.E.A. Projection clock costs ¥15,750 (appx. $133 USD), and can be found on the Transit website.
