Visitors to this year’s Chelsea Garden Show were left scratching their heads by an unusual fountain created by none other than inventor James Dyson. Inspired by the works of MC Escher, the water in the fountain appears to flow uphill, cascading over the top of a series of four ramps. Wrong Garden, as it’s called, actually took about 12 months to design and build, and the secret to how the illusion is accomplished is spoiled revealed in the above illustration from BBC News. Basically the laws of physics are left in tact, but compressed air is used to create bubbles that provide visual clues that the water is flowing uphill, when in fact it’s not.

A few blogs are passing around videos of the Ishikawa Komuro Lab's high-speed robot hand performing impressive acts of dexterity and skillful manipulation. However, the video being passed around is slight on details. Meanwhile, their video presentation at ICRA 2009 (which took place in May in Kobe, Japan) has an informative narration and demonstrates additional capabilities. I have included this video below, which shows the manipulator dribbling a ping-pong ball, spinning a pen, throwing a ball, tying knots, grasping a grain of rice with tweezers, and tossing / re-grasping a cellphone!

THE BUSHBUDDY (REGULAR MODEL), IS A MORE RUGGED AND LOWER COST ALTERNATIVE TO THE BUSHBUDDY ULTRA, BUT STILL WEIGHS ONLY 6 1/2 OUNCES
About the BUSHBUDDY
Like the Bushbuddy Ultra, this stove was designed to provide the cooking needs of one or two people, but can also serve the needs of a family or small group if two stoves are carried.
It weighs just 6 1/2 oz, and makes a compact package 4 1/4" in diameter and 3 3/4" high when nested (the same size as the Bushbuddy Ultra), which will fit inside the Snow Peak Trek 900 titanium pot, and many other pots of similar or larger capacity. It's compact size and light weight make it ideally suited to the needs of the backpacker, cyclist, and other outdoor travelers. Because it burns wood, it is a very economical stove to use.
