After Touch Press' astonishing Solar System app, I've been keen to see what the agency has been up to since. I was belatedly catching up with the latest issue of Wired this morning on the tube and it turns out the company is working with cover star Bjork.

I've always been a fan of Iceland's greatest export since she was lead singer of the Sugarcubes. She's an incredibly inventive musician and a great visual artist. Her videos, particularly those directed by longtime collaborator Michel Gondry, are memorable and beautiful - Bachelorette is my particular favourite.

For Bjork's latest album, Biophilia, she wanted each song to emphasise a key idea, whether it was tempo or arpeggios, while lyrically focusing on scientific ideas (not quite Jessie J territory then). However, she wanted to provide an experience for the album so people wouldn't just head to Mediafire and download it. Originally, she proposed a music house, with each room designated a different song with interactive elements relating to the track. She also planned a 40 minute 3D IMAX Bibliophilia movie, directed by Gondry. However, as Gondry got bogged down in filming the absolutely dreadful Green Hornet movie, he had to drop out.

Exit Gondry, enter the iPad. After its launch last year, Bjork began exploring musical apps and it dawned on her that fans could have the same experience in the music house but by using apps. This is where Touch Press came in. Each song was contracted out to a bunch of iPad app developers. Touch Press has put together two apps for the album - Crystalline, where the user can mix up the song phrases by navigating a crystal through a set of 3D tunnels and Hollow, which shows DNA replicating in sync to the song. You can (thankfully) listen to the tracks in a conventional way as well. Development wasn't cheap - the two apps set Touch Press back a cool £120,000 on research and development.

I want to spend more time playing with the app before I write a review but this is an excellent example of how artists are rethinking their content in the digital age. It also reinforces the argument that books are no longer competing with other books but other forms of entertainment.

Touch Press has shown with the Elements and The Solar System how books can be repackaged into dynamic content. I'd love to see a fiction author attempt to do something similar to Bjork. Maybe Jennifer Egan, who played with style so well in A Visit from the Goon Squad. Or Mark Z Danielewski, whose House of Leaves ignored all conventional narrative rules but remained a fascinating read.
