Clock and art

When I was on the airport I noticed a clock. It was a big one! And they had made it look like it just had the tick marks but no hands. But that there was a man standing inside it, on the other side of the translucent face, with a bucket of paint. And that every minute, he painted the long hand into the inside of the face. And then he would scrape off the paint again. And paint a new hand. Et cetera! I liked it. So it gets its own blog post! Albeit that it shares a day with another one...
