The Memento lamp was designed by Hiroshi Yoneya and Yumi Masuko for design collective Tonerico. At this point, it looks like it’s is only available in Japan.
When completely closed, it measures just 2.75? tall (and looks like a high tech stapler). Open it up, and it can reach up to almost 22? in height. This beautiful design doesn’t come cheap, the price is $595 USD, but if you want something cool and elegant you have to pay the price.
Hurdle Lighting was designed by Koreans Lee Suk Woo and Byeon Dong Jin, and received a Special Mention in the 2007 Lightouch Design Competition in Singapore. The light structure is designed to stand either horizontally (like its namesake) or vertically, more like a desk lamp.
Transparent House isn’t providing directions or even saying if they are selling these, but the idea’s simple enough I imagine anyone could make this work with a little bit of elbow grease.
