On the 4th of December, I started experimenting with spirals for this drew various spirals out on tracing paper and cut them out and test the LED and shadow effect.
To create a final spiral design I took some strong wire to build a support structure, next I took a long piece of wire and made a long spiral and glued tracing paper around it and glued small spirals on it, next I hooked it to the support structure, then I managed to place the LED inside and wrap the positive and negative wire around the neck of the support, once the wires were connected to the transformer I managed to create a spiral shadow from the bottom.
