By the time of writing, the project is undergoing its first beta phase. I noticed several room for improvement here:

• Change the LED to a red one. White LED often contain phosphor on top of the silicon substrate to make it emit light with spectrum what our eyes see as white. This phosphor layer will glow for a short time after current removed from the silicon ("afterglow"), potentially affecting accuracy of the rotation simulation. This effect does not appear on the plain red LED.
