This is great, I've been thinking in a similar about something like this for 'visual debugging', for a livecoding tool.

It would be great if this could recognise some common image formats in memory (cairo surfaces, PIL) and visualise those on mouseover.

Possibly similar for arrays - be able to visualise it as a wave or even playback as audio.

Is there any chance of factoring out the support for the popouts? - It would be great if this could appear in other editors.

I'd love to do live variable inspection (like the Chrome Dev Tools) — it's something I'm thinking about for the future.

There's a (nascent) project called `jmp` (for Jupyter Messaging Protocol) that implements kernel communication in JS: https://github.com/n-riesco/jmp. I'll probably contribute to that and factor out my kernel communication.

I'm starting up a way to do this with an Electron app (the base of Atom), called Jupyter side car. It's not ready yet, but will share some of the same components. All this is pretty exciting for the Jupyter project.
