Translating data from sources such as human development index from different nations into audio files.
For example one parameter could be the average life expectancy in a certain country - sets the length of the audio file, 80years = 8 or 80seconds.
In the end there shall be audio files which each describes a country, the better the life - higher salaries, higher education, intact environment - shall produce an audio file that sounds very harmonic and warm, whereas nations with short life expectancy, lots of crime and death shall produce a noisy, distorted soundfile.
Can use synth or might even work with sound samples.
If this sounds intriguing, you are very welcome on board :)
