Artist Maarten Baas has a project called “Real Time” in which he creates one-of-a-kind clocks using a video camera and boatloads of patience and dedication. He creates 12-hour-long loops of people manually setting the time on various clocks… in real time. The video above shows his grandfather clock exhibit in which the hour and minute hands of the clock are painstakingly drawn in every minute of every hour for twelve hours.

Here’s the same idea done, except it features two men sweeping lines of trash that’s arranged in the shape of a clock:

He also has an analog clock version (this one’s also available as an iPhone app):
