Could you expand on this? It can help to use (hint-origin) to visualise
the local transformation of the primitives - the axes give you an
indication of what calling translate will do (the direction of x,y,z and
the amount it will move due to scaling).

Navigating the scenegraph with (get-children) is a good way to do this.
You could also use the mouse to pick primitives with (mouse-over) and go
up or down the scenegraph running various scripts on the objects.

I can't get anything funky to happen - could you post a screenshot?

On the flickr pic, it looks like you might have blur active, tiled
framedump won't work with that currently (and I'm not sure if it ever
will, as it reuses the same render target to make each tile)

It seems to work here with your tree script as it is tho.
