Mother Night, by Noboru Tsubaki

This year's Roppongi Art Night -- an annual all-night outdoor art festival featuring installations and performances at various locations in Tokyo's Roppongi district -- took place this weekend.

The centerpiece of the festival was "Mother Night," a 13-meter (43-ft) tall spaceship-like balloon sculpture by artist Noboru Tsubaki. Stationed at Roppongi Hills Arena, the imposing work monitored the carbon dioxide emissions of the onlookers and displayed real-time data on a built-in projection screen.

But perhaps the most rousing event happened at the nearby Tokyo Midtown mega-complex, where French street theater troupe Compagnie des Quidams performed their dreamy "Rêve d'Herbert" piece, featuring larger-than-life bubble people with heads that glow.
