Hi,
I've posted drafts of my talks for SVG Open 2012 (now known as "The Graphical Web") to my website. Comments welcomed. I give both talks Tuesday morning in Zurich.
The talks use JessyInk and require you to hit Page Down twice to get to the first slide. Firefox messes up some figures while Chrome doesn't do indenting text spaces well.

Looking good!

About tensor product meshes vs. "auto-smooth": tensor product meshes /can/ exactly reproduce the "completely smooth" gradient you show (the one from Israel Eisenberg). The earlier examples I gave simply only enforced matching derivatives across edges, if you also enforce matching derivatives across the center point, then you get the attached image, which seems to be indistinguishable from the one that was found by Israel Eisenberg.
The advantage of doing it the "tensor product way", is that you can simply support the same kind of interface that we currently have for choosing a node type: corner, smooth, symmetric, and possibly even auto-smooth (only in 2D).
Of course there is still the matter of how to deal with "out-of-range" colour values (on handles). But I think this need not be insurmountable (specifying out-of-range colours need not be a problem per se, and for display one could simply clip for example).
Any way, have a nice time, and lot's of luck with your presentations!
