DIRTY WINDOW

I'll get around to cleaning all my windows soon and when I do I'll be able to out-smug any bug in any rug - won't want to know myself.

Thing is - I seem to have acquired a weird fascination for the patterns left by water droplets on glass...

They're so regularly irregular - they seem to give me confidence that nature knows what its up to - and will forever remain beautifully inscrutable. Like DaveH's batty cat!
