One example is algorithms heavy code. There are already numerous resources(e.g [1]) that visualize algorithms and data structures. If those kinds of animations could be generated on the fly, it would be much easier to write that kind of code. Being able to visualize code blocks (kind of like Light Table) and move them around between files, maybe even modify inheritance structures graphically could be useful too. Seems like there are a lot of cool things you could do, but IMO the challenge is coming up with a few things that are actually useful for a significant amount of code and yet remain possible to build.
