Question : Looking for bicycle cadence indicator using colored LEDs to show speed

Am posting here after unsuccessfully searching for this everywhere. What I am looking for is a cadence indicator which would display speed as a color. The output would consist of an array of LEDs of different rainbow colors. As pedal speed increased, different colored LEDs would light up. This would be a very simple way to know your cadence as you would not even need to really look at it directly.

Basically a tachometer set up like a vertical VU meter.

Any ideas?

Thanks.
