think of it as the 3 wire runs into the top of the icycle, and a tube tube extends that has leds, but not the chip. the chip would still be at the top of the tube, and the three wire comes out the top also, running to the next icycle.
buy doing it this way, I have control over how the icycle looks. i can put as many leds as i want in the tube, they can be single color, or rgb, they can be close together,or have some spacing, and they can be 12 inches, or 6feet long
