I admire Apparatus which was brought to my attention by Bret Victor, whom I also admire. Been thinking about how I might connect apparatus to wiki. site 
Reviewing commits from earlier this year, I noticed a thing about a "viewer". Not much in the way of docs, but looks like there are tests. So... create a plugin which includes the viewer. commit
Apparatus itself wants a whole browser for editing. Graphics editing inside a wiki page seems quite limiting -- not enough screen real estate. But while I was browsing the code and tests, I did find docs about self-hosting an installation. I containerized apparatus for use in a local installation: Container dobbs/apparatus
Many months ago I created a model in aprt.us to help explain why programming around time is so painful. Well, maybe I created that more so I could have a tool to think with next time I needed to reason about time-related code. Either way, I learned how to save and load my explorable. So... maybe create a transporter for moving a saved model into a wiki
Based on today's (2017-08-16) hangout, there may soon be a good home within wiki for storing assets. So the transporter could save the .json file from apparatus into this assets folder, and the plugin with the viewer could load that .json from there.
