I don't think this guy qualifies as most people, seeing as how he's a mathematician who also created this: http://maxwelldemon.files.wordpress.com/2009/06/penrose-tile...

Did he proclaim he was creative? Did he even use that word to describe his fabrication?

Interestingly, you'll notice he did, but only when he was discussing his teaching ability...

I find them to at least be nice.
