I'm likin' this lichen

Ouch, sorry!

This is a twig from a fallen tree in the garden. The twig was lying across another tree stump and I liked the way the different species of lichen were alternating along it.

I used one of Gavin Hoey's triptych actions for PS and did quite a lot of tweaking to get this result.

Go on, have a peek at the large version.
