One of the first activities I saw was Function Carnival, and I was blown away.
Unfortunately it hasn’t been updated to use the new tools and I see now it is being retired at the end of 2020.
I’m wondering if
(a) anyone has written an activity that is as close as possible to the original one?
(b) anyone would volunteer to write such an activity, especially if Desmos were to make available the images they used in it?
