Looks like a less feature-full version of livecode [0], which I'd argue is more of a HyperCard successor", since they were formerly revolution & MetaCard, and can import HyperCard stacks.
I found a path from Piano to Volcano with 40 generated topics!
Piano → Instrument (broader)
Instrument → Juilliard School (places)
Juilliard School → American conservatories (past)
American conservatories → Historic music conservatories (past)
Historic music conservatories → Paris Conservatoire (places)
Paris Conservatoire → European conservatories (broader)
European conservatories → Europe (broader)
Europe → Sicily (places)
Sicily → Mount Etna (similar)
Mount Etna → Volcanoes of Italy (similar).
I've been looking forward to watching these, since last year's. Some really interesting projects this year. The feeling of computing[0] (formerly future of coding) community is also a great place for live programming and related topics.
