Just came across Lua-Quick-Try-Out, it’s another example of live programming, it allows you try out lua algorithms instantly, since you can see the result lively.

Live coding has really become hot recently since Bret Victor’s Inventing on Principle talk.

This kind of examples are proofs of live coding, which is one of the main feature of LIVEditor – the new text editor for the web with a Firebug-like UI for trying out css styles, html and js codes lively (thus quickly).
