    Awesome! Gotta make me one of those- oh wait- you need sunshine. Hmm. I'll have to wait til summer. Until then, I have an idea- make up a continuous long strip of clear plastic that has an ever encreasing bevel angle on one edge. Then you wind it into a flat spiral and it becomes a giant fresnel lens.
