GUIs - ruby on rails, rico

[bryan rasmussen]

If you're talking about what I think, the Canvas as an editable vector
graphics area is part of the whatwg specifications
http://www.whatwg.org/specs/web-apps/current-work/

whatwg has various browser manufacturers/implementors as part of their
group, but not IE.
It has not been finalized in their specs yet IIRC thus given this I am
not surprised as to the lack of examples as yet.
