Okay, I had a little time on my hands while waiting for a service man to arrive this morning, and I decided to figure out how I embossed a photo a couple years ago (click to refresh your memory). I figured it out, began playing around with other special effects options, and ended up with...Well, a series of modified pictures is worth a thousand modified words. I give you Fun with Fish Eye (and Circular Wave).
It's probably a good thing the service man came fairly early in the promised two hour window. Who knows what I might have come up with if I'd had more time? *shudder*
