That's fine in all you want to achieve is filtering effects but that doesn't
fit with the examples shown by Adobe. They're morphing the content in 3d.

In one case they're morphing something to look like a newspaper. It unfolds
but is still interactive once it unfolds.

In another case they're morphing a twitter feed a kind of wavy shape and
they are interacting with it while it's in this wavy shape. I don't see why
the user would think it's not 100% interactive.

So it seems like for this proposal to be generally useful that content needs
to able to be interactive (ie, the user needs to able to click on stuff just
like they can with 3d css). Otherwise the number of use cases for it seems
exceedingly small.
