I was thinking about the Olympics(who isn't?) but that entails too many people shots, so I think I will go with Rings.
This can be circles or in fact anything based on round shapes.
Yes Rings is it!

What a pity I didn't photograph all the cows I saw recently in Auvergne. They all had bells on theie necks, and were ringing away merrily in the mountain pastures ...

Guess i'll just have to think of some other rings ...

This should fit both themes The Olympic Rings on my red mittens! These were produced for the Winter Olympics in Vancouver, but I have seen some on Canadian fans in the crowds in London!

Tree trunk cut up into rounds.

Rings around drawings to make signs on the Llandudno tram car.

Calamari in huge pans at a local festival.

Looked through some old photo's for this theme and found this photo with the figure made into a round shape from a 2010 holiday.

I have posted moon gates before, but not this one, in a local park. It looks like it is a mirror but you can walk through to an equally lovely garden

The moon partway through an eclipse

How about the real Olympic rings?




I was round the back. At the front there was a huge queue of people wanting to have their photo taken with the rings, hence in my pic you only get silver rings and there is someone you can't see holding up the Union Flag, lol.

Same rings - different city. These are in Athens.

These are five rings I use for the joining rings magic trick. Please don't ask me to demonstrate it, it's been many years since I've performed.

Wall grate on an old house.

Here's an O-ring I found on a tree in the gardens of the Chateau de la Vigne (France):

Shall we have another moon photo? The full moon in April, 2012.

Wow, nice photo of the moon. My piddley litte camera can't focus in that good. All I get is a yellow blur!

Well. later today I will close this thread with its clever interpretations of the theme of Rings. Thanks all.
New thread is entitled "Cool".
