Oh yes, I have a fair amount of 'yard art.' It is definitely more to the informal, country, whimisical side, some might call it kitschy.
For example, I have a sundial, 3 bird baths in various gardens, a 2-tiered fountain (these are nice), an old wagon wheel, an old water pump (country), a toad house, various statues peaking out here and there, quite a few bird houses on the fence posts, wind chimes, and even some old candlesticks (3 different sizes together) with colored marbles on top instead of candles. Oh also have a gazing ball. Many of these items were rescued from Hurricane Katrina and are not in the best of shape, (like the candlesticks) but they are valuable to me and each piece really tells a story. Like the wagon wheel was given to me by a dear neighbor, who we don't see anymore due to the Hurricane. But I am definitely a bit kitschy, even nailing my first Mississippi license plates to the fence (have a magnolia motif in the center) when they replaced the plates with the Biloxi Lighthouse (love those too). And don't forget a bottle tree with colored bottles to catch evil spirits, a very (informal) Southern gardening thing.
I like the ideas that you have for your yard art, definitely more refined and I think would be lovely. I am not sure I would have the discipline to pass up all the cutesy novelties I see, I even recently had to retire a dying plastic pink flamingo!

I love how everyone is inspired by diffrent things for their yard art.
Id love to see your bottle tree Laurie! Ive seen people use a lot of things for the 'tree' part, what do you use? Plastic things kind of weird me out, but I always thought it would be neat (if you really liked color and really like flamingos) to have a whole flock of them, but paint each of them a diffrent color, with the regular pink one leading the pack!

Only two. A birdbath and an antique stone trough.
All I want (and can't buy here) are English staddle stones. Real antique ones, not reproductions.

Ouch, what a price!! Cute though. I don't have a lot yet. My fences, split cedar rail, qualify I guess. They add structure. I definitely like stone or cement, and use large pots for colour punctuation. Some of the pots have fanatastical insects on stakes, kinda funky, but too out there. Everything that I'd really like is out of my price range!!! I just keep searching flea markets and yard sales.

Two bird baths and a repro weathervane.

Some one I knew lived in a neighborhood that had a flock of (plastic) flamingos that roamed.

Someone would wake up to find them in their yard. Several nights later, they were supposed to put them in someone else's yard.
With out getting caught.

My bottle tree is made out of rebar. It's pretty neat. Came across some right after I moved here, had to have it and brought my sister one, she lives on the Miss. coast. It's fun finding pretty bottles for it, the most desirable bottles are cobalt blue, hard to find, and can be expensive.
