We present a twistor correspondence for half-flat almost-Grassmannian structures on real manifolds. An almost-Grassmannian structure is (essentially) a factorization of the tangent bundle, which determines two preferred families of tangent subspaces, and this structure is said to be half-flat if one of these families is integrable. We provide global results when the underlying manifold is a Grassmannian of 2-planes, and show there exist nontrivial deformations of the standard almost-Grassmannian structure. Whereas twistor constructions typically involve moduli of closed curves in a complex manifold, we utilize and expand upon the more flexible approach pioneered by LeBrun and Mason using moduli of curves-with-boundary.
