Nano-Posters?

In the Technology Review section on nanotech this week, there is an article about a "solution of nanoscopic iron oxide particles" that changes color in response to magnetic fields. Using variable, controlled magnetic fields, this liquid can be changed to any visible color. One of the practical applications mentioned is "as pixels in rewritable posters or other large displays."

Think of all those bars that could change the cover price for entry in response to nightly attendance:

Empty? "No Cover!"

Packed? "Cover: $20... and deadly good looks."

iBot Sighting

In LoDo last week, I saw an iBot, which is inventor Dean Kamen's answer to the wheelchair. Try to forget the media circus that took place around the Segway, that silly little scooter (Remember the code name "Ginger" and the idea that our mail would one day be delivered by Segway-driving postal workers?). The iBot is truly amazing; it provides transportation to those who can't just go out and buy a skateboard.

Using gyroscopes, the iBot balances its user high up on two wheels (at eye-level). Best of all, the iBot can take people up stairs. I even found video of a man in an iBot at the shooting range.

Jeff Han: Perceptive Pixel

Jeff Han, the founder of Perceptive Pixel and the creator of the multi-touch interface now being seen in the iPhone, is featured on the Technology Review website today. He talks about the simple idea behind his interface - moving away from the single point interface, as with a mouse arrow - and instead choosing something that gives users a more natural and intuitive response. He mentions that part of the goal is to develop a presure-sensitive interface.

This reminded me of the progression from the harpsichord to the piano, which, for the first time, allowed 18th-century composers to write in an important musical dimension: volume. The action inside the piano, which strikes the wires rather than the plucking motion of the harpsichord, allows the pianist to play loudly or softly.

Animaris Rhinoceros Transport

From the Strandbeest website: "Since about ten years Theo Jansen is occupied with the making of a new nature. Not pollen or seeds but plastic yellow tubes are used as the basic matierial of this new nature. He makes skeletons which are able to walk on the wind. Eventualy he wants to put these animals out in herds on the beaches, so they will live their own lives."

I've seen a lot of robots walk, but I've never seen anything look so life-like that didn't require thousands (if not millions) of dollars worth of programmable motors and processors. These are wind-powered and absolutely gorgeous.

If these three things are seemingly out of reach creatively, try your own hand making an articulated machine with SodaConstructor, a software that allows the user to build and run virtual machines.

The Onion Weighs in on The iPhone:

Ah, The Onion. Perfectly put:

iConcertCal

This weekend, I found out about iConcertCal, a plugin for iTunes that uses your music catalog to search for local concerts. Pretty dern cool.
