Livecoders merge programming, music composing and performance all into one. What I linked above is their manifesto. It would be probably difficult to achieve such an amalgamation of math, coding and art. There has always been a deep connection between math and music, and there is a ton of work out there on music theory and math, or even on algorithmic music. What I have in mind is something different. Consider for example this stunning visualization on primes. But how about more contemporary structures: finite simple groups, algebraic K-groups of integers, Adams spectral sequence or even torsion parts of homotopy groups of spheres? What would they sound like? Something to ponder. In the meantime, you may enjoy listening to “Day of the Triffords” by Andrew Sorensen.
