Cat collar buckles

[c-in-hiding.livejournal.com]

I'm designing a bunch of cat collars, inspired by the lovely Mr. Manny Ramirez (that's him in the icon), and I'm having trouble finding buckles. At first I was looking for the ones that look like a belt, but then discovered breakaway buckles, which open and let the cat free if the collar gets stuck on something. But, well... they're kind of ugly. Does anyone know of some more aesthetically pleasing breakaway buckles, or have any suggestions as to how to spruce these ones up?
