A Ferrari headlamp.  This thing is absolutely incredible just to look at, and photographs even more jaw-droppingly.  The technical details are amazing, and this car is almost over-styled.  The more you edit a pic of a Ferrari, the better it looks, but after my usual coupling of HDPro and Contrast, repeated in layers about 4 times, I settled on this.  A little Astral Glow and voila.

All PaintFX or course, you can probably chant the above filter names along with me.
