Electro Maze

Electro Maze is an electronic maze. A little yellow light (LED) is provided
on a business card, together with a printed circuit and a battery.
The object of the puzzle is to connect two adjacent tracks with the yellow LED,
such that it lights up. Next, it should be done such that also the red LED
lights up. Then that the green LED lights up. Then that both red and green
light up together. One needs to solve the maze holistically to find the
spots where LEDs can be lit. Oh, and the puzzle is also a regular maze that
can be solved from entrance to exit. The pattern of the maze is based on the
famous dragon's curve.
