Although I should be slow to tie myself down to a specifics at this stage I had a look at some Generative music pieces. Brian Eno s one of the pioneers of this style of music. He has made a big impact with his music apps. His apps are very interactive, touch based affairs, take for example Bloom:
This is an interesting approach to generative music but not the one I'm looking at at the moment. I also came across another iphone app called ANTracks on the ACM database. '... describes a generative music composition application on a mobile phone. Music generation is a well-suited application domain for multi-touch and reality based interaction. Thus, we choose to implement our concept on Apple's iPhone/iPod touch. Based on selected harmonic scales the user creates a musical expression by controlling a number of virtual ants. The movement along pre-defined patterns allows users with little artistic talent to create harmonic expressions. The mobile device can act as a multi-touch input device that controls an electronic synthesizer program on a desktop computer or as a stand-alone application.'
This again relies on a touch interface but the ants can wander by themselves (according to an algorithm) and only trigger certain notes. It is these two aspects I am interested in. Originally my idea was to reflect the emotional feeling of twitter but that would be rather restrictive. After research into digital art the best pieces are interactive. So I'm now leaning towards the same idea (art from twitter feeds) but instead of restricting the field to predefined words I'm considering letting the word that's being searched for to the user, so instead of searching for 'sad' they could search for 'john', either way, art will be created.
