More balls than you’ll ever want

Half a million colorful toy balls rolled around in the middle of Rome today. Most sightseers in Rome expect to see ancient monuments and whatnot (such as the location of this prank, the 18th-century Barcaccia fountain), but perhaps it’s also home to a growing number of entertaining “street art” performances, to put it lightly.

Last October, a vandal / genius artist turned the 18th-century Trevi fountain blood-red as a sort of social commentary on the Rome Film Festival. No word yet if today’s prank is a protest against Chuck E. Cheese.
