This Ferrofluid is a magnetic fluid. On these towers (one of the features at wired’s NEXTFEST 2007) the ferrofluid actually reacts to sound. Soon you will be able to buy these. The white background is actually fluid in a well that has a light shining on it. It seems white because the fluid is incredibly reflective. The bad thing is that they take up a small table and you cant touch them or put metal near them.
The final showdown is under way in our first-ever Gadget Freak of the Year contest. Who will win an all-expenses-paid trip to the Pacific Design & Manufacturing Show? It's up to you, dear readers, to tell us.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
