Still, we all respond to things differently....
I often find myself most moved by abstract forms. Thomas, the Mandelbrot example was a good one, as an example of something abstract and very powerful... I'd consider mandelbrot zooms/explorations to be a very human thing, though. They create meanings in the same way that music does- the relationships of parts to each other and to the whole. And is music human? tone relationships are cosmic (physical/mathematical), like the mandelbrot set itself. Composition, on the other hand, is a series of decisions, much like the zoom/exploration of the fractal, and can be related to our lived experience of being in time as well as anything, in my opinion. These meanings, these abstract explorations of the human will, tend to give me the most sublime experiences (music, mostly- but also moments of abstraction in other forms... musical play).
Anyway, in short, I like the sound of your failed project, Michaël, and might enjoy playing it quite a lot more than you, even Have you considered putting the prototype online?
