Beautiful/Crazy/Tacky Thumb Drives

I came across this page by accident. I love these objects, but I have no idea if they are one of a kind, or how they came into existence. I have asked the other blogger for an explanation, but since it is a non-English blog, I'm not expecting an answer.

These are just two examples of what I found on the page. I should look for other tricked out "thumbs."
