Time is a funny thing. Sometime you need to know exactly what time it is, and sometimes you really don’t care. For the times that you don’t care, a clock that tells you roughly what time it is more desirable then a perfectly accurate digital clock.
The Sander Mulder concept clock is an example of this. It’ll provide you with an approximate time based on the poem that is printed around the edge of the clock. The bad news is that it’s a concept item and may never actually make it to retail.
