That gibberish on a blackboard is actually a clock, made by Dutch industrial designer Christiaan Postma. He used over 150 individual clock mechanism to spell out the hour!

I do like this clock. I think it's because I get the sense of about what time it is instead of the exact time. Since the arrival of the digital display I feel inundated with the obsession to know the exact time. I feel a sense of freedom when I go through my day without caring what time it is. This clock would help me keep that feeling while providing a gentler and sometimes necessary reminder of the time of day.
For instance:
It's about four.
and not
"At the sound of the tone it is exactly four thirteen."
And come on, if after owning the clock for a day or two you can't approximate how closely the hands are to forming the letters withing (a very generous) fifteen minutes, you probably should just have a big digital watch anyway and forget the "hands" style altogether :)
This is a very clever art piece.
