Interactive wetropolis in browser?

Wout Zweers visited the Rhino Developers day in Amsterdam Nov 2018. A very intersting new development is the possibility to run an interactive model in a browser (like Chrome). It is a alpha tryout,  it may enable showing the waterlevels and the sliders to change the amount of rain, or generate rain randomly and see what happens.

This would make it possible that many people can play with the amount of rain and see what happens with the river.
