Torch/beacon. The torchknob version is for platforms with no buttons, like the Numworks on Android. Ask for inputs or use defaults.
"""Torchknob (Torch-no butttons)
This version is suitable for devices with limited io
such as Numworks (so cannot use keydown buttons to change color or brightness).
Asks for blink, color and then runs (or defaults).
(Use blinkmax to minimise Numworks reinstalls).
