There is only one metric for code quality. WTF per minute. Start the timer, read the code, press the counter button on every curse you yell. The app calculates the WTF/Minute for you.
The lesser the number, the better the code. Let's hope for 0 WTF/Minute.

The Mengenlehreuhr was situated in the middle of the Kurfürstendamm in Berlin, Germany. I can still remember my Mom and Dad explaining how to read it. My Grandma always peeked at her watch to tell the time :-)
The rows read as follows
- the dot flashes once every 2 seconds
- 1 rect = 5 hours
- 1 rect = 1 hour
- 1 rect = 5 minutes
- 1 rect = 1 minute
Add it all up for the time.
