The World of Music


The World of Music, originally uploaded by densitydesign.

We began using the ratings from 150,000 users from Yahoo! Music LAUNCHcast. Users rate music on LAUNCHcast using an intuitive interface. The ratings then influence what music their customized radio station plays.

Afterwards, we used the user ratings to compute the similarity between the artists. Essentially, for each pair of artists, we counted the number of users that rated both artists highly to determine the similarity. This operation gave us the artist-artist similarity graph. In the image below, we show the clustered adjacency matrix of the graph. The blocks you see in the middle of the picture are similar groups of artists. (In fact, this is how we got the color for each artist in the final picture.)

To determine the layout, we used an optimization algorithm based on semi-definite programming to compute a layout of the graph on a sphere. The layout algorithm tries to find good ways to split the data and naturally separates different groups of music. (In this case, the most natural separations are musical genres!)

Once we had the layout, it was constrained to lie on a sphere. We then “unrolled” the layout to get the image above. (That’s why some of the “routes” look like airplane routes — they are great circles!)

Collaborative Storytelling Experiment


The Cambrian Game, originally uploaded by densitydesign.

Unblokt.
This is a sort of experimental interactive creativity, in real time. You can write a sentence trying to connetc the previous sentence whit the next one, suggested by the software. Six books are already completed, these are the titles: Volume 1, Volume 2, George w. bush speech, Dear John, Letter from camp, College Woes.
Now are coming 11 stories: general (6.1%), adventure (3.5%), historical (2.6%), horror (2.8%), sci-fi (2.4%), fantasy (2.9%), mystery (7.6%), crime (3.1%), humo(u)r (4.3%), romance (2.9%), erotic (3.1%)

The Cambrian Game.
The Cambrian Game is the game in which players can submit their own leaf to the tree in the virtual space. You can link a new leaf to any leaf which you are inspired by. A leaf can trigger some leaves, and the tree will grow explosively.
The Cambrian Game Series in EXPO 2005 Aichi is a continuous series of Cambrian game sessions with a variety of ideas.

Experimental Social Inteface


Locus, originally uploaded by densitydesign.

Locus is an instant messanger, social experiment, and art piece that is built on the premise that you are how you act.
By examining how you and your friends talk with each other, Locus automatically tries to find likenesses between your friends. You can then see these potential relations mapped out for you! You can watch your social web grow as you speak.

State of Information Vol.II


Vanishing Point, originally uploaded by densitydesign.

The goal of this project is to decipher the world that news media reconfigures and to observe if media coverage, or lack thereof, is creating a new cartography.

Vanishing Point consists of a map of the world connected to a database fed by news coming from several international newspapers. The visibility of each country on the map results from the quantity of media coverage the country receives, so those countries that do not make the news disappear progressively.

State of Information Vol.I

From Influx division of BSSP newsletter

Information implosion
“Every event has thousands of commentators all offering a different perspective. Every protest has more photographers than protestors. Every one of us has the chance to be heard.
It can’t go on like this. Only 14 thousand of the 19 million blogs on Bloglines have more than 50 subscribers. It’s cool that everyone can do it, but if no one is listening or no one cares, it becomes self-defeating.
Beyond those with a desire to reach out and show others how great or how creative and interesting they are, are people simply going about the business of documenting their lives. It’s been predicted that every family will need a terabyte of storage in their lifetime to store all their personal media. So they spend their lives recording and storing.

There’s just going to be too much stuff.

We need editors.

Consumer control is fine, but there is just going to be too much stuff to look at and listened to. Doesn’t it get dangerous when Starbucks sees music overload as an opportunity to dictate taste? Even the editors have gone over-choice crazy — how many channels are there on Sirius?
There needs to be a really sophisticated personalization layer that helps find the stuff you should see and hear. Nothing comes even close to this yet; Tivo’s recommendations don’t really work, and even Netflix leaves a lot to be desired. Is anyone doing something interesting in this area that we are missing?”

the state of the blogsphere
“Technorati has just published its latest report on the state of the blogspace, its findings make for interesting reading.
The highlights:
– 19.6 milion blogs
– A blog is created every second
– 8-20% of blogs are splogs or fakes
– 9 posts are created a second
What’s most interesting is that growth in postings per day seems to be in decline. Postings peaked in July with the London bombings at 1.2 million/day, but are now around the 600,000 level. Although Katrina did create an increase in the number of blog posts, this increase has not been sustained and the volume has fallen back.
Blogging is not going away, but it does seem that its explosive growth appears to be slowing down a little”.

Describing the world Vol. II


“Everything-I-Touch”., originally uploaded by densitydesign.

Jan Chipchase’s photo-ethnographic research strategy “Everything-I-Touch”.

“Using a digital camera, the participant is asked to take a photo of everything they touch for at least half a day sometimes from the moment they get up. If you like user research data, the results are a rich orgy of the mundane. The method was successful enough in achieving its original aims, but also yielded other interesting data such as highlighting the flow of the day, the order in which tasks were completed – people likely to pee before checking the weather in the mornings, and understanding the range of contexts where the user spends time.”
