A super simple web page based timer with a buzzer for UI GIS Day 2017 lightning talks.
Only works in modern browsers.
I use it on Firefox, full screen mode, on a touch screen laptop, folded in stand mode, making a lovely timer for an event.
Use: Click "Ready" to start; at the end click "0:00" to reset. Defaut is five minutes with a caution color at two minutes and warning color at one minute. To customize the time, add "#" with time,warning (for example, one minute with warning at 30 sec: lightning-time/index.html#60,30).
Inspired by and based on timer and lightningtimer projects.
