Trees are in Fashion?

I couldn't help noticing so many of the works in the January round of UWA competition featured trees. I think the works are removed to make way for the next round in a couple of days- so make sure you get there to see.

As well as the works above there are also tree works from Alizarin Goldflake and Araminta Kroitschov.
Great to see so many works based on trees, and such a variation in approach to this universally recognisable object.
