Complex Simplicity

I suppose I could ask the question: What is this..?? ... (answers on a post-card, etc ...) ... but because I'm such a cheapskate, I couldn't be bothered to lash out on any elaborate and expensive prizes ... So instead of putting this blip forward as a competition, I'm just going to tell you what it is ... (even if most of you have probably already guessed) ... :o)

It's fine rainwater (aka: drizzle), on a spiders web (the sort of spiders web that looks more like a ragged piece of old net curtain), on a bush (a green one) ... :o)

So no prizes either, for guessing what the weather was like this morning ... :o(
