Mysterious objects

We saw three of these odd looking objects as we were driving through New Hope to pick up Manny's car. Shayna and I were intriqued as to what they could be. A house for Gnomes? Fairies or sprites? Shayna deduced that sprites and fairies are too small. On the way back, we had to stop and take a closer look. Here is a photo of one of them:

We did find out what they were. If you want, take a guess as to what they might be. I'll post what they are in a few days!

UPDATE:

The objects are a work of art/sculptures inspired by Monet's haystack paintings. They are made with wire framing with a gauzy hay like material on top.

Go here to see one of the hay stack paintings:
