Offline using your code, if I replace this code,

<iframe src="http://games.greggman.com" width="100%" height="100%"></iframe>

with this code,

<iframe src="http://css-3d.org/" width="100%" height="100%"></iframe>

I have a perfectly accessible page. I can navigate the iframe to access 
the demos.

If I have this code,

<iframe src="http://www.google.com" width="100%" height="100%"></iframe>

it also seems to work as I can hover links, insert text into the inputs 
and navigate the iframe. I can even perform a search.

The only thing I can activate with at http://games.greggman.com is the 
text and submit inputs via tabbing.

By my experimenting via elimination, I would suggest that there is no 
issue with CSS3 3D transforms but something wrong at your domain.

I did another test by loading google in the iframe offline. I searched 
my name and went to my domain. I then went to the links section on my 
home page and followed the link to the www-style archives and found your 
message (the one I'm replying to now). I then selected the link to your 
test. To my amazement your domain became active. All the links work, the 
hover events work. Oddly though, I am accessing your domain by way of an 
iframe within and iframe.

Can you please point me to a page that shows how to morph like that (the 
webkit prefixed code would help)?
