people are asking me.
what practical use can the ITSY pack be used for?
and i wave my arms about and list all kinds of vague notions of what can be done.
but i fail to impress!
so…
for me the new vistas opened by @Bill_French and @Paul_Danyliuk work is this
“interactive visualisations”
user moves things about on the screen with the mouse (or finger) and the values in the coda database are changed accordingly. values change in the database and the visualisation reflects that. all in real time.
think brillian.org or explainabl.es but in coda!
THAT is a mission worth all my midnight oil for the next many months
