Is it?...

Very convincing.

Convincing, sure, but honestly not that surprising. The latter portrait of DaVinci as an old man has been widely accepted as a self portrait for many years, and is it honestly so hard to put together the similarities in facial structure? That being said, however, I was pleasantly surprised to see the Vitruvian Man in a new light.

That was really interesting....

Very interesting. I am convinced he is right!

This specific video was great. But, the whole site (TED) was awesome. I watched several of the video lectures, and was amazed and entertained!

Thanks so much for this clip!

Marcariel, TED is indeed a great place, i love prowling its goods
