Cyril is a new tool, that enables you to live-code visuals. It is based upon OpenFrameworks, has its own, easy to learn syntax and it’s still early in development. I will definitely keep my eye on this.
Somehow I disliked most of “the other” live-coding tools like Fluxus or Overtone, because of the cumbersome syntax of the scheme/lisp-derivates.
PS: Did I mention, that I work on an own live-coding tool in Ruby with PureData as backend? Check out SuperSonic (still alpha) and get updates at my Nodepond-blog.
