Clock by Christiaan Postma

The word “three” completely appears when it’s exactly 3 o’clock and will then transform again as time passes. The word “four” begins to appear and at exactly 4 o’clock the word “four” is clearly visible. The word “three” is by then totally vanished and no longer readable.

I must say, it is a great piece.
