Most of the trees on Philip's Creek have been created in part by using twisted wire coated with Liquid Nails and then painted. I used to feel that the twisted wire was a bit obvious and not a true representation of the way a tree grows - but no longer.
This tree was photographed last weekend in a carpark opposite Hornsby RSL. Unfortunately, although you can see some twisting in the bark, it is not as pronounced as it was a few weeks ago when I first noticed it. Still, from now on, it's my prototype tree.
