A broken piece of red plastic tail-light with refracting prisms. Turned it at an angle to the sun to make it partly transparent. Used mini-tripod and timer, but had to hand-hold the subject material.
I was "on location" and had nothing to remove the bits of dirt, so I tried to de-emphasize them with an oval vignette, darkened and blurred a bit.
