Frivolous? i think not! Life is ordinary and ordered enough that it needs a bit of the unexpected now and again to delight the imagination and shift things a little. Safe, fun and serendipitous enjoyment to make the heart sing! I'd love to come across a flash mob someday too. Bhttp://www.youtube.com/watch?v=7EYAUazLI9k
I LOVE it. I really enjoy surprise installations. They are a pleasure.
