A clock the reacts to the change in time (self aware)!
The 24-Hour clock is a result of our experimentation with color changeable LED's or pixels, similar to the ones used in display systems. The pixels are arranged in a way that they act as a 7-segment display used in digital clocks of the yore.
The surprise in this system is that it changes color with time and your presence . This experiment in color changing capability is allowing us to develop intelligent lighting solutions for our projects.
