And if you fancy a unique free ring tone Xmas gift for your mobile what could be better than WolframTones? The ringtones are an experiment in applying Stephen Wolfram’s discoveries to the creation of music. To explain:

“At the core of A New Kind of Science is the idea of exploring a new abstract universe: a “computational universe” of simple programs. In A New Kind of Science, Wolfram shows how remarkably simple programs in his “computational universe” capture the essence of the complexity–and beauty–of many systems in nature.

“WolframTones works by taking simple programs from Wolfram’s computational universe, and using music theory and Mathematica algorithms to render them as music. Each program in effect defines a virtual world, with its own special story–and WolframTones captures it as a musical composition.”
