Variable fonts have a proposed new mechanism, a version 2 update to the AVAR table, to allow variable fonts to fence off unusable portions of the designspace, and otherwise distort the mappings. About AVAR2: https://type.today/en/journal/avar

For the bleeding-edge font folks… @lorp has a new tool for experimentally testing and modifying variable font AVAR2 mappings with interactive live visual output. You can drag mappings around AND then export the modified font! Wow.

@tphinney It must be fate… at tonight’s art exhibition at Spike Island open studios is a hand-made hexeract, or 6-dimensional cube (well technically one feeble projection thereof in 3-space), that I must think about as a UI for Fencer. It won’t confuse anyone will it?
