Talk about moving mountains. Many of today's most sophisticated shooters trumpet destructible environments that let you splinter walls or pulverize pillars into powder with a well-placed salvo. But none offer the freedom or flexibility to reshape the world around you like LucasArts' new futuristic blaster Fracture ($60, PS3/Xbox 360). You must morph terrain in real-time to tunnel a way forward or stop bullets from dinging your bionic rear-end.

Forget the carbon-fiber bike that costs more than your house. How about one made of plastic? The Innervision bike is a design concept by industrial designer Matt Clark that ditches high-cost complex materials for pre-molded plastic parts.

Music can inspire much. It can evoke emotions and insert itself into our memories—but even Tom Petty ain’t getting me through 26.2 miles. Half that? Maybe. That's what the scientists behind yesterday's "Run to the Beat" half marathon were banking on by including 17 bands along the London course that were systematically chosen to distract runners from the misery of the moment.

British sports psychologist Dr. Costas Karageorghis helped pick the individual tempo, genre and location of each band to best benefit the runners.

Even the fishermen are going green. Any angler worth his bait has lost a few lines to the bottom of the fishing pond. And, chances are the line he lost is still lying there with those of his ancestors, damaging coral and killing fish. Traditional nylon lines can take up to 600 years to disappear, but with Bioline, a new "biofilament" line developed by alumni of the med-tech industry, that time can be cut to just five years. That's fishing technology even the fish will embrace.
