- The traces aren't too dense, and have really interesting shapes.
- The PCB is translucent, giving the light a really nice hue. These are from some sort of mixer and are very hard to find.
- You can see just a few components that were left on the inside of the lamp, silhouetted.
UPDATE: I went ahead and put in a tall, 36W CFL. The lamp is a lot brighter and lights up evenly, now. I posted an instructable on how to do it.
