Mechanical Letter Countdown Timer

This is a mechanical clock built based on a flexible countdown timer for Hype written by Jonathan from Tumult (https://forums.tumult.com/t/a-flexible-countdown-timer/9665).

This extends the base code with the usage of a Symbol and mechanical animation. It fires a custom behavior called “timerExpired” when time is up. This also serves as an example to create reusable Symbols.

There is a variation in there that uses two letters per mechanical display. I prefer the single digits but in some cases you might need the variation.

Download for free by entering zero. I'd appreciate if you return and re-download it for a fee if you're using it commercially, it's valuable to your work or it helped you make a profit.

Much appreciated.
