IEEE Spectrum's monthly slideshow proves that a picture is worth a thousand bytes

This ornately detailed figure, which brings to mind the beauty of a coral reef, is actually a 3-D computer rendering of a mathematical equation. It’s an example of a fractal, which breaks the rules of traditional geometry because its area and perimeter are incalculable. Fractals defy number crunching, because no matter how closely you zoom in, the features look like ever-smaller copies of the entire figure.

We’re tantalizingly close to having robotic household servants. Mahru-Z [right, with “older sibling” Mahru-M], an automaton developed by researchers at the Korea Institute of Science and Technology, can clean, put your dirty clothes in the washer, pop your snack into the microwave, and bring it to you. The 1.5-meter-tall domestic is the result of a two-year project.

Yes, there’s a hand sticking out of this guy’s shirt…well, no, not really. It’s actually an optical illusion generated by software that aligns the computer-created arm with the window in the shirt (sent to subscribers to T-Post magazine). A webcam allows wearers to see themselves and the hand on screen and play the classic kids’ game Rock, Paper, Scissors. Remember: Rock beats scissors.

Engineers at the Institute for Automatic Control Engineering at the University of Bremen, in Germany, have developed a set of robot arms that can be attached to a disabled person’s wheelchair. The extra set of hands could aid patients whose hands are paralyzed or extend their reach, allowing people to grab things from high shelves or off the floor.

The trackball and the touch pad were slight improvements over the computer mouse, but they still require unnatural hand placement. The wireless AirMouse, which will sell for US $129, lets you point and click whenever it senses that your fingers are extended and your palm is flat. Otherwise, it’s inactive, so it won’t intrude when you’re typing or thumbing through a file drawer. Photo-illustration: Deanmark

What better way to observe primates’ natural behavior than by giving them a new toy that doubles as a monitoring device? Researcher Betsy Herrelko of the University of Stirling, in Scotland, got a wealth of footage showing the inner workings of chimp society when she left a chimp-proof video camera in an enclosure at the Edinburgh Zoo. The animals gave Herrelko an unprecedented chimp’s-eye view of the world.

Green power begins with a protective coating of what will eventually be part of a 44-meter-long blade on a wind turbine. The workers are employed by Vestas Wind Systems, a Danish company whose Chinese subsidiary has sold more than 1000 utility-grade wind turbines in China.
