OK, I've updated the "WIP" binaries with the new "ZPoints" stuff, including the "Tweener"
New screenshot (Updated - "Refresh"if you don't see Godzilla)

Yes, those are warped videos.
and the
MXM_Skin.xml used....
Look at it for an example of how to do the ZPoints and Tweener modifiers. I basically created a layout in Corel Draw, rotating my blocks, then exported as a 640x480 jpg, and used the pixel positions for each corner to position the text element ZPoints.
The tweener is a bit crude at the moment. I am considering expanding it to allow multiple "tweens" - Instead of A -> B, you might have A -> B -> C -> D, but the tweening looked good enough in my test.
