Step 3Electronics
There are several ways on getting the layers lighted up one by one. I wanted bit more control and made
a little circuit by using Atmel's Attiny45 to drive the leds with PWM signal. One could use for example 555 timer chip in combination with 4017 decade counter to advance the animation one step at the time.

Hm... I have to say that I don't even know. As the leds get only arond 20mA each at max., the wire does not need to be that thick. Even the wrapping wire will handle the load.
