Hmmm.. I would say Apparatus is no longer under active development. Researcher Joshua Horowitz was doing some work on it for a bit, but yeah I don’t think it’s changed much in several years. It should be regarded as a research project that scouted out several areas of the “programming experience” world that others can build on.
FWIW the aparatus site says
> Apparatus is under active development. Discuss how Apparatus should evolve on the Apparatus Google Group.
Which seems like it's no longer accurate. Has it moved to a different repo?
