A big circle on which travels a dot representing the current second. You can zoom in to see the segment of the circle the dot is near. The more you zoom in, the faster the dot travels because the current line represents a shorter timeframe. I was inspired by Lera Boroditsky on the podcast saying that when you’re looking at a line you might be looking at a piece of a circle, when they were discussing linear and circular time.
An ink-plotter makes a dot at every 5-minute-mark on a typical clock display, beginning its process at 12am. For every subsequent hour, the dot size increases. You can tell which 5-minute mark its on because the dot will be larger than those of the later times. You might be able to approximate the hour based on the dot size if you are used to this timekeeper.
A webpage that first allows you to choose between two questions, and then displays the time.
