Somewhere deep in the heart of Felix Labs and Entertainment lies a handful of developers (presumably) who were tired of the typical ho-hum address book. Possibly because of their work making Human Computer Interaction hardware, and possibly because of the excessive rain in British Columbia, they decided that contacts should be represented as popularity balls, and that each ball should be moveable not only with your finger, but also with the accelerometer.
The key to the app is definitely its simplicity. Without any additional input, Filter Fish grabs all of your contacts and seemingly sorts them by popularity and relevance. For example, if you type in the letter "t," your little contact globules will reposition themselves in order of relevance. Type in more letters and you'll see the irrelevant globs fall off of the screen, leaving your desired contact front and center, or wherever you want to fling it. Type in nothing and the app will show you a mighty universe, one that has your close friends as huge planets and your minor contacts as space dust, all ready to be moved around with a ferocity that can only be described as Biblical.
Oh right, you can also click on the globules to retrieve contact info, but I had much more fun creating a spinning universe of my friends names.
Being more of a tech demo (I think) than an app that will get a ton of usage right away, Filter Fish is a great little product, and one that I would like see expanded to do even more. One thing that I would love to see is a company function, allowing an extra large 148apps (acting as the sun) to be circled by all of its employees. Extra little features like this will do wonders for Filter Fish, and I definitely hope that it lives on to reach its true potential.
