Hi Meurig and fellow eCraft2Learners,
I am very sympathetic to the theoretical ideas around construals (and constructionism). I am unclear if the idea is very different from what
Alan Kay calls Active Essays [www.playfulinvention.com] and Bret Victor calls Explorable Explanations [worrydream.com]. My recent favourite
of such things is the Parable of the Polygons [ncase.me].

When the topic of tools for authoring and sharing such things comes up one needs to carefully compare JS-Eden, Mathematica, Jupyter,
D3.Express (still in alpha but given the success of D3 [d3js.org] this could be very good), Scratch/Snap, NetLogo Web, my ToonTalk Reborn
[toontalk.github.io], and probably more.

CONSTRUIT Conference looks good -- I'm considering it.

Best,

-ken
