Here is another one.

Was just thinking, instead of having an hour glass (highlighted in the previous post) or having a marker thingy / loading bars (as pictured above), why not just make it numeric? It’s called – KEEPING IT SIMPLE

Something like – Keep a 2 position system. Top for Stop, Bottom for Go and instead of displaying just a solid colour, it displays a countdown timer.

Would be large enough to be readable. The different positions would make it usable for the colour blind as well and there would be no need for an extra display unit to show the timer.
