Quick update:

Just came back from Quo Vadis 2013 in Berlin where I talked about "C++ on the Web" in front of a crowded room (thanks to all who've been there :), the slides are here:

And I have moved the Nebula3/emscripten demos to my own web site here:

http://www.flohofwoe.net/demos.html

The demos at the old appspot.com URL haven't been updated in a while. When I get around it I'll redirect to the new demo page from there.

Over and out :)
