my screen name is in reference to the great Leonardo Da Vinci, who, now that I think of it, among other things, (artist, songwriter...) was what we today would call a bit of a geek. Imagine if he lived today and he had a blog, now you know he WOULD have one! He'd probably write articles like these:

How Long Does Bill Murray Spend in Groundhog Day? (yes I read it yesterday and I was just waiting for a chance to post it)

I've used this name elsewhere, sometimes going so far as using a picture of Leonardo as an avatar; it has no relation to my real name, but I've used it so much it has become my second identity, even so that I'm considering adding it as a second name to my real one.
