For every event that occurs, people point to something Nostradamus said and claimed that he predicted it. Sure, what Nostradamus actually said was very vague and can be made to fit a huge number of events, as no astrologer worth his salt would be too specific for fear of losing his job.
It also seems that for virtually every technology that comes out, DaVinci managed to invent it a long time ago. Sometimes it's obvious, but it sometimes it seems it's all about interpretation. Sure the device in his drawings could possibly do this or could possibly do that, but is it really so or are people just wanting it to be that way? It seems to be a lot of interpretation, and I've heard so much of it, I'm starting to become rather sceptical.
Similar to this, Christian fundamentalists love to quote Bible verses to "prove" their point. Not only do Bible verses not hold any water with me, but it seems like anyone can find Bible quotes to support virtually *any* view they have. It would surprise me if there were verses from the Bible, which interpreted in the right way, would support baby sacrifice or atheism.

As for automata, it wouldn't be at all surprising for DaVinci to have done entertainment automata. It was one of the few things you could sell in the court-patronage era of mechanics. Understand that in that era, science, art, and mechanism design were hobbies of the rich. This was because you can make beautiful little mechanisms out of brass with hand tools and time, but to make power machinery that does useful work, you need an industrial infrastructure. That didn't come until much later.

1. Da Vinci is, like, one of the foremost intellectual figures of the Italian Renaissance, which is a pretty important period in history, especially as regards culture and technology and stuff.
2. One of the most interesting things about the invention of the computer is not the various engineering challenges such as how to build the logic gates and stuff, but the initial idea that computation itself can be usefully reduced to a physical, deterministic process. If, back in the 15th century or whenever, there was some guy thinking along the lines of encoding machine-readable data in the for of little bits of carefully-crafted wood, then, even if the idea didn't work, the fact that he had the idea at all is pretty amazing and has all sorts of implications for the Renaissance concept of the mind, of logic, etc, etc.
3. One of the reasons that Da Vinci's inventions are so famous is that, while they are obviously shockingly ahead of their time, no-one knows in many cases whether they were ever built, whether they worked, or even what they were for. Any progress in unravelling these mysteries is a significant step towards understanding Da Vinci himself (For the point of this, see point 1 above).
4. It's a mediaeval-style robot. Not only is this self-evidently cool in itself, it also has major implications for Dungeons-and-Dragons-playing Slashdotters, who can now, with an arguable degree of verisimilitude, introduce clockwork robot buggies into their campaigns.
