suck air in & blow air out.
Air filters suck air in & blow air out.
Computers get filled with dust & particles.
Why not combine computers with air filters and turn your computer into an air purifier? Not just small filters on those little fans that you see on most computers, but a large fan & air filter outside the main beige box. Many air filters are about the size of a computer case, and it would be easy to make one that simply attaches to a computer case.
It could move much more air than a standard case fan, keeping the computer much cooler and cleaning the air at the same time. It may use a little more electricity than just a computer, but not more than a computer + air filter would already use, and perhaps just a bit less because you won’t also have to run case fans.
This is really cool. Similar to How Happiness is Reflected in Blogs, this website creates a map of human feelings from blogs. It can be sorted by age group, gender, geographic region & weather on that day. And the UI is cute too, though I wish it were more useful. Check out the Findings.
Since August 2005, We Feel Fine has been harvesting human feelings from a large number of weblogs. Every few minutes, the system searches the world’s newly posted blog entries for occurrences of the phrases “I feel” and “I am feeling”. When it finds such a phrase, it records the full sentence, up to the period, and identifies the “feeling” expressed in that sentence (e.g. sad, happy, depressed, etc.). Because blogs are structured in largely standard ways, the age, gender, and geographical location of the author can often be extracted and saved along with the sentence, as can the local weather conditions at the time the sentence was written. All of this information is saved.
The result is a database of several million human feelings, increasing by 15,000 - 20,000 new feelings per day. Using a series of playful interfaces, the feelings can be searched and sorted across a number of demographic slices, offering responses to specific questions like: do Europeans feel sad more often than Americans? Do women feel fat more often than men? Does rainy weather affect how we feel? What are the most representative feelings of female New Yorkers in their 20s? What do people feel right now in Baghdad? What were people feeling on Valentine’s Day? Which are the happiest cities in the world? The saddest? And so on.

This is a really cool approach go designing with restraint. Any decent musician can tell you that you can’t make everything loud and still give emphasis to the beat. There need to be spaces or nothing will have impact. The same goes for design - the more space between objects, the more emphasis each object can have.
This, then, is an exercise in restraint.
The difficult part about designing for attention isn’t deciding what to talk about—it’s deciding what not to talk about. Because you only get a potential customer’s attention for a few seconds (if you’re lucky enough to get it at all) you don’t have luxury of rambling. You have to cover your key points with both speed and strength.
