When is a picture of a clock more than just a picture? When it's actually a real clock. The Real Time Canvas Clock is a stark picture of an old-timey desk clock, except this picture shows the actual time — mounted flush to the canvas is a real clock mechanism.
The clock runs on one AA battery and the clock's mechanics are accessed from the back of the canvas. This simple work of art will set you back $36. While all the world is going 3D, it's nice to see some good old-fashioned 2D media catching our eye.
