Rain. Downspout. Catchment basin with spilling water, moss, and I kind of don't want to know what else.
The basin's on my list for cleaning.
I had some other options this rainy morning: twisted green garden hose with dripping water, still life with hapu, garbage bag, and rebar, and carpenter bee poop (years of it) on a white wall.
Oh, why not? Click through to the rejects if you want.
