The internet may have given music fans unprecedented access to the world's music, but finding it in any kind of organized way can be a challenge. Now providing a location-based approach comes CitySounds.fm, a music browser that streams the latest music of the world, city by city.

Created by a Swedish duo for Music Hack Day last month, CitySounds.fm lists major cities from around the world, with those most frequently selected at the top. Listeners simply click on a city name to hear a selection of the latest music from that city. All of the tracks played come from professional audio platform SoundCloud.com, while photo images accompanying each city name come from flickr. Using CitySounds.fm is free, and tracks and cities are updated constantly to reflect each city's musical trends.

Like Harman Kardon's trip planner with suggested travelling music, and Louis Vuitton's MP3 tours of Chinese cities, CitySounds.fm provides consumers with a way to connect sound and music to specific places, whether or not they're travelling there themselves.

Although street art is experiencing a renaissance, the old issue of vandalism remains. YrWall is an interactive virtual graffiti wall that avoids the drips and damage because, quite simply, there's no paint involved. Users paint on a projection screen using a can that's actually an infra-red beam controlled by a button and tracked using a computer vision system. By pressing the faux spray can's button, users draw on the wall much like using their computer's draw function, but without the mouse and on a much larger scale. A pop-up interface provides an array of digital paint colours and also allows users to select themes like nature or urban; grabbing images from these themes to add to their piece.

YrWall, which can be hired short- or long-term or installed bespoke, has already been quite a hit at events like the UK's Secret Garden Party. Adding to the concept's appeal and branding opportunities, people can receive a free digital copy of their art to share with friends, or can have their design printed on t-shirts and stickers right after they've finalized their piece.

While YrWall isn't going to eclipse the interest in genuine street art and good old spray-can graffiti, it’s an appealing mix of physical and digital, and of performance and play. Which could make for an irresistible offering for event organizers and their novelty-seeking clients.

Consumers can already tap the wisdom of the crowds for advice about their image, their style or even their marital disputes. Now taking the notion a step further, Instant Jury gives them a way to resolve conflicts of most any kind—marital or otherwise.

People stuck in a dead-end argument about virtually anything under the sun can open a "case" on Instant Jury to bring it to "the court of public opinion." Current examples include a disgruntled man who claims his female coworker cheated to win a sales contest by wearing revealing shirts, and another man who wants his neighbour to buy some headphones while he's learning to play guitar. Users of the site choose a username, give their case a name and description, and then list the stakes—lunch, for example, in the case of the sales contest dispute. Once that's done, the defendant in the case receives an email asking them to participate—also anonymously, via the username of their choice—and give their own side. If they agree within 24 hours, the case becomes live and both sides get the chance to present opening and closing arguments in their defense, as well as uploading supporting evidence such as photos, emails, etc. The jury—made up of at least three interested visitors to the site—then "deliberates" and casts its votes, leading ultimately to a final decision; if fewer than seven votes are received, the site's resident "judge"—dubbed "Hugh D. Cyde"—gets the final say.

Potential jurors can search for interesting cases by category ("classmates," for example, or "office politics") as well as by descriptors including "Ending Soon," "Cold Cases" and "Most Viewed." They can leave comments as the case progresses, and each case they serve on earns them juror credits that increase their rank and—ultimately—will get them special privileges. Ad-supported Instant Jury is based in New Jersey. One to localize and bring to the bickering masses near you...?

Much the way Webkinz pets are more than just stuffed animals, so t-shirts can be more than just t-shirts when they forge links to the online world. The conversation-starters offered by Reactee, Shyno and Augme are one type of example; now bringing a new purpose to such connections comes The Music Tee, a shirt that gives wearers the right to free music downloads.

The new offering from Invisible DJ and fashion house LnA features album art on the front of the t-shirt and a list of tracks on the back. Included on a separate hang tag, meanwhile, are a URL and a unique code that can be used to download one copy of each of the tracks printed on the shirt. The first such unisex tee features an eclectic compilation of artists from around the world, curated by Invisible DJ; with 14 tracks, it's priced at USD 60. The second Music Tee—due to become available on July 7—features The Ecstatic by Mos Def. With 16 tracks, it costs USD 39. Both are available exclusively at Ron Herman and LNAclothing.com.

Band t-shirts have long given fans a way to visibly proclaim their musical taste, but bundling with downloads adds an extra incentive for consumers to buy, and at a considerably higher price. Indeed, the OFF=ON connection is giving companies in industries far and wide new ways to connect with customers—not to mention new revenue streams. How about your brand...?

Two years ago, we covered a few mobile services that help users find the nearest public restroom. Focusing instead on when to go, RunPee is a web-based service and soon-to-be mobile app that maps out loo-break moments for popular movies.

Users can choose from an extensive list of movies currently in theatres, and a few classics like Aliens and Star Wars. A time graph of the film indicates when it's safe to disappear for a minute or two. The website lists a cue line to listen for, and the approximate amount of time before something important happens. For those who want to find out what they missed, a box of scrambled text can be clicked on to reveal what was missed. The site will also note if there's a scene after the credits, so movie-goers don't run out of the cinema before the film is actually over.

Anyone can contribute suggested break times to the listed films, which as they say, makes RunPee a Wiki-pee-dia of sorts. (Sorry…) An iPhone application is currently awaiting approval from Apple, meaning weak-bladdered users will soon be able to check in from the theatre. Which is, of course, where the concept shines. One for drinks manufacturers to sponsor, encouraging sales of 48-ounce colas?
