Here's another example that's starting to work, though it isn't flashy yet.
http://hashcollision.org/tmp/js-get-message/js-get-message-parent.html
I know, I don't have any design sense yet. I need help. :)
The first half of the window is a simple web-world program embedded in
an iframe, whose source is:
http://hashcollision.org/tmp/js-get-message/js-get-message-child.rkt
The second half is just honest-to-goodness plain JavaScript in
js-get-message-parent.html.
Typing a message and submitting at the bottom calls HTML5's
postMessage, which sends a message over to the web-world program. The
web-world program responds to postMessages, and incorporates it into
its world.
Note that the postMessage support is _not_ built in! I'm using our
experimental FFI bindings to hook DOM message events into the
web-world. See the top half of js-get-message-child.rkt for the
minimal postMessage bindings.
