Is it art, or was someone with a nail gun bored? While it must have been the result of prior planning, still there is a delightful sense of whimsy here. How many bottlecaps go to waste, when these are living the life. I esspecially like the random[?] interplay of primary colors next to the grass and cement and wood.
Keep on creating, people. Public and free (while still not featured in the Smithsonian collection) art has been on the rise and it adds a little something wonderful and new to the day.
