Aboriginal Art ?

No. This abstract image is actually of the tracks left by beetle (or moth) larvae as they burrow under the bark of a fallen gum tree. The bark has now fallen off, revealing the tracks.
Photo taken at Kingston Beach, Tasmania.

A big thank you to all who viewed and commented on my 100th blip they are much appreciated. In fact, a big thank you for all your comments and support from blip 1 onwards.

I am now worried that there will be great disappointment once I return to Scotland next Wednesday and I revert to more mundane subject matter.
In fact Wednesday may be a blank day as I believe we will be en-route for 22 hrs so I may not be awake enough to operate the camera.
