>Things like Jupyter (formerly iPython) come close, but still can't do things like render video. This isn't actually true, you can render video in the notebook with matplotlib, although it can be pretty cumbersome. We've been developing a library called HoloViews (http://ioam.github.io/holoviews/ http://ioam.github.io/holoviews/), which makes generating complex visualizations and animations in the notebook a breeze. We support video output, widgets, gifs etc.
