I just learned about live coding the other day! What a cool intersection. From the wikipedia page:

Live coding, sometimes referred to as on-the-fly programming, just in time programming and conversational programming, makes programming an integral part of the running program.

It is most prominent as a performing arts form and a creativity technique centred upon the writing of source code and the use of interactive programming in an improvised way. Live coding is often used to create sound and image based digital media, as well as light systems, improvised dance and poetry, though is particularly prevalent in computer music usually as improvisation, although it could be combined with algorithmic composition.Typically, the process of writing source code is made visible by projecting the computer screen in the audience space, with ways of visualising the code an area of active research.

Here's a Tedx Talk:

and a GitHub repo with a bunch of resources for anyone who wants to give it a try:

If you're a live coder, please share your videos! I'd love to check them out.
