Braid developer Number None appears to be getting into motion control for one or more potential titles. Dev head Jonathan Blow has posted a job listing seeking a programmer to perform “very interesting work in full-body motion tracking.”

This could be for the revealed but much-unknown project The Witness, or for a completely separate unannounced title. It was mentioned previously by Blow that Witness would contain motion control in “only a limited way.” Whether things have changed between then and now is currently unclear.
