This is a switch which could be triggered by human touching the feather.

I did spend some time thinking about the circuit of how can make it work. First I know that I need parallel; But where to put the break (switch) and also incorporate with the aesthetic placement of the LEDs is a little bit tricky. I only want to light up one LED at a time when the feather touching on one corresponding switch. Finally the circuit work out like this:
Start placing the LEDs on the wood sheet. Facing different directions to light up.
Adding feathers layer by layer.
Be careful and delicate with the aesthetic and circuit.
