The BE Light can be folded down flat to a minimum height of 1.8 cm! And it can be fully extended to a height of 33.4 cm, and an angle of up to 135 degrees. It’s made out of aluminum. LEDs. 
It looks nice.

At face value these small hand-carved wooden sculptures by scientist and artist John V. Muntean appear to be a random amalgam of mixed geometric shapes, curves and holes, but shine a light at the right angle and suddenly in the objects shadow is a discernable image. In fact, each sculpture contains three images, usually revolving around a theme. Via his website:

A Magic Angle Sculpture appears to be nothing more than an abstract wooden carving, skewered with a rod and mounted on a base. However, when lit from above and rotated at the magic angle (54.74º) it will cast three alternating shadows. Every 120º of rotation, the amorphous shadows evolve into independent forms. Our scientific interpretation of nature often depends upon our point of view. Perspective matters.

Muntean has numerous videos showing how each piece works, I definitely recommend spending a few minutes poking around. You can also follow along via his blog, and inquire about purchasing a piece.

“Global Rainbow” by Yvette Mattern is a massive scale outdoor light projection in which seven high power lasers project a rainbow light beam for up to five miles. The projection was originally displayed in New York in 2009, and is currently on tour through the United Kingdom in celebration of the 2012 Cultural Olympiad.

I’m one of those grumpy old people who waxes nostalgic about Super Mario Bros. because I haven’t attempted to play a video game since my college days when I burned a few good brain cells playing Mario Kart on Nintendo 64. So while I don’t “get” today’s realistic games, I most certainly appreciate this lamp that’s fashioned after the coin blocks that appear throughout the Super Mario series. Available from Etsy and made to order, the 6×6 inch plexiglass cube lamp is actually interactive and features a touch sensitive bottom. One punch…err, touch and it will light up while playing that classic “coin” sound. Even cooler, every 8 cycles, you’ll get a “1-Up” sound instead

Japanese artist Makoto Tojiki works primarily with light, exploring its use in installations, figurative sculptures, as well as kinetic pieces. His No Shadow works shown above are among my favorite, using long strands of lights to create representations of people and animals. See much more over in his gallery.

The Defender by Gotham Bicycle Defense Industries is a theft-resistant bicycle light with a design inspired by the cylinder of a revolver. The light’s creators, Brad Geswein and Slava Menn, are raising funds for the project on Kickstarter.

The Neoline Lamps are minimalistic neon hanging lamps that bring to mind classic crystal chandeliers but have a modern appeal due to modern design by BOA, founded by Czech designers Peter Mikošek and Michael Vrátníková. Click here for the link.

The Light Blubs are a series of crystal lamps, designed by Pieke Bergmans, in cooperation with Royal Crystal Leerdam. The lamps are all unique handcrafted crystal pieces, equipped with leds by Solid Lighting Design.

German-born, Australia-based lighting designer Volker Haug designed this quirky lamp that features individually hand-cast porcelain components glazed in brown and white. The fixture was inspired by double adapters and, of course, reindeer. The Rudolf Lamp is available through Matilda Design as wall mounted or a hanging pendant. The perfect light for when you want a holiday look without a sleigh and reindeer.
