Unfortunately, none of those ideas will qualify - they are just simple ON/OFF blinkies. Take a look at the attached drawing. The horizontal axis is time and represents the blink rate. The vertical axis is the LED brightness. The post that you linked to is like the upper trace. What I am looking for (as in the video above) is shown in the lower trace.
Also, the blink rate (or period) needs to be adjustable by some method of your choice. A minimum of 4 LEDs/channels are required. The blink rate of each LED needs to be adjustable independently and should not affect any of the other channels.
