The Sun Cube is a prototype timepiece that uses highly precise and complicated principles of celestial geometry to tell the time. At first glance, it looks like nothing more than a solid block of metal with a bunch of holes punched through it. However, the hundreds of dots are actually cut to match the exact angles of the sun passing overhead.
The Sun Cube was created by Toronto-based artist Daniel Voshart. He isn't throwing away his watch just yet -- the Sun Cube only works within a 100-mile radius of Voshart's father house, as the celestial geometric angles it works off differ based on location. Also, it can only work for 40 years because of the fact that the Earth's axis is slowly shifting. But it will even pose inconveniences this year, since it can't correct for daylight savings time. However, there's no questioning the fact that the Sun Cube is a product of complex science meeting ingenious design.
