I’ll go with answer A, originally uploaded by Shiny Things.

What is this a photo of? Is it:

A) A psychologist’s inkblot;

B) A complicated stalactite formation in the Jewel Caves of south-west Western Australia, formed over hundreds of thousands of years by calcium carbonate leached from limestone; or,

C) H.R. Giger on a bad day?

More Jewel Cave formations here and here; some pics from the Cape Leeuwin lighthouse (the furthest southwest point in Australia)… and some creative road sign defacement.
