Altitude's Product Innovation Roundup - A Weekly Helping of Coolness

Top off your week with these latest cool happenings in the world of product innovation and design:

• We love this new concept by Evan Gant. The Sprout attachment re-purposes an empty milk jug into a versatile watering can. [video]

• Ikea adapts to a world in which e-books are becoming increasingly popular and people are starting to use their bookshelves for things other than books. 

• The United States of Design, "...American design is having global impact in everything from fashion to human/machine interfaces, system design to artisanal craftsmanship, health-care devices to, yes, that miniature watch/alarm clock/pedometer/music player on your wrist."

• Dyson Unveils $400 'Jet Engine' Space Heater, jet engine technology in a sleek home appliance.

• Get excited about Windows 8 and Metro and what it means for you, even if you're a loyal Apple consumer.

• Another simple, yet genious way to re-purpose a plastic bottle. This "solar bottle" brings light to those who have no electricity, and helps others save on their electric bill.
