A few folks have mentioned the weird trees going into the Columbia Heights Civic Plaza at 14th/Kenyon/Park, mainly asking what in the world they are.
They kind of look like flowers or trees, and looking at the plan (below right) for the plaza, that appears to be what they are. Here's another view. However, the other plans don't seem to show them, instead having some kind of sail type thing.
Personally I'm going to reserve judgement on these until they get finished, but they are a bit weird. I hope they put in real trees also.
Here's the plan's website. It's supposed to be finished this summer.
UPDATE: A commenter says the designer told her the things are LED lights and solar panels, which will partially power the fountain. Pretty cool.
