If you could mix your bicycle with your car, you might get something like the Firefly by Geospace Studio. With a protective shell that illuminates with LEDs for knight night riding, could the Firefly become a fun, environmentally-friendly alternative to a car, and a warmer, more visible, all-weather option to a bike?

Top Secret Drum Corps is a precision drum corps based in Basel, Switzerland. With 25 drummers and colorguard members, the corps became famous for its demanding six-minute routine performed at the Edinburgh Tattoo in 2003. With its invitation to Edinburgh, Top Secret became one of the first non-military, non-British Commonwealth acts to perform on the Esplanade at Edinburgh Castle.

CLOUD is a large-scale interactive installation by Caitlind r.c. Brown for Nuit Blanche Calgary. Created from steel, metal pull-strings, and 5,000+ light bulbs (both illuminated and burnt out) CLOUD asks the viewer to participate by experiencing the work first hand – standing beneath the structure and pulling lights on and off, creating the flickering aesthetic of an electrical cloud.

This engineering marvel is called “Clockwork” and was built by K’nex enthusiast Austron, who has built five K’nex ball machines. This one is his most ambitious endeavor: 

It took 8 months to build, has over 40,000 pieces, over 450 feet of track, 21 different paths, 8 motors, 5 lifts, and a one-of-a-kind computer-controlled crane, as well as two computer-controlled illuminated K’nex balls.

Thanks, @RaySadler.

This is the swima bombiviridis, a bioluminescent “Green Bomber” that was found in deep Pacific waters in 2009 by Karen Osborn of Scripps Oceanography. From ScienceMag.org: 

Thousands of meters below the sea, a tiny worm wriggles through the darkness, its dozens of paddle-shaped bristles moving in beautiful coordination. Suddenly, a hungry predator appears. The worm releases a glowing green sac, and the fish homes in on this bright new trophy. By the time the fish realizes the sac is no meal, the worm is long gone.
