This will probably remind my British visitors of something! I found these big plastic balls in front of the Hotel de Ville (town hall). They are actually targeted at kids who take great pleasure in moving them from the inside. I must say I was tempted too - but I'm way beyond the age limit! They are probably part of the Paris Plage program - which goes now much further than the river banks, but I could not find anything about them on the Web...
