Angels?

These wind turbines are on top of Australian Catholic University. I see them on my way into work, whilst at work, and then on my way home again.

I've tried to blip them many, many times (even stupidly threw away an amazing shot with an aeroplane in it in favour of a different shot), but they've never made the grade.

I decided that today was the day, with the hugely ominous clouds lurking behind. I'm not sure whether they're supposed to represent angels, but they're certainly mesmorising to watch spinning round!
