While watching Tron for the umpteenth time, I started thinking about how data could be displayed in abstract, but still readable, ways. The OLED display, with its crispness, seemed like a good fit for what I had in mind. After considering a few different options, I settled on building a stylized clock display.
You will need:
The blocks are drawn so that, from outside to inside, each ring represents hours, minutes, and seconds. The time is read with 0 at the top left corner. The current hour and minute are indicated by the empty block in each ring. The current second is drawn as a solid block (this ends up looking like a square moving around the inside ring). In the above picture, the time can be read as 8:23 and about 38 seconds.
