This is something curious that really impressed me, mostly because something synthetic does what would actually be realistic and expected.

Towards the end of the video (1 minute mark) a Windy Day is shown. I found it uncanny that the tree plausibly moves to the wind audio file. Reminded me the first time I say leaves being swept across the ground in Heretic.
Well and letting the user draw a tree outline to have that automatically create a 3D model is also nifty.

Cool thing in itself but especially that windy day looks more like a tentacle monster than a tree...
