Large Revolving LED Coin Help

A microcontroller is definitely within question for controlling the device; the accelerometer will be used to wake the device, and the gyro will be used to measure

when the device has rotated a certain amount. The device is meant to be spun when held vertical, similar to the animation above. The sensitivity of the gyro would

need to accurate enough to recognize medium to fast movement from someone spinning it under normal circumstances (in their palm).

As per LEDs - if an LED matrix (9x8) were used, they would need to be fairly low power. As someone has recommended, edge lighting may be a possibility
while being much more energy efficient. The immediate issue that I would probably run into would be light bleeding through the darker sections. Assuming I went

with that design, I would probably opt to go with some sort of glossy plastic cylinder. The top and bottom would use a layer of dark/black acrylic with two sheets

behind the M and N side and one behind the O. I'm not quite sure if two extremely thin sheets would have bleeding issues. A possible fix would be narrowing the

lighting angle.

For power, I intend to use a battery; the battery would need to fit within a 2.5 x 2.5 x 1 space alongside the other components. For all other specifics, I'm not

entirely sure. I apologize for the nondescript hardware references; I'm without a clue which pieces I would be looking for.
