We describe a geometric construction, using certain Springer fibers, of a modification of Khovanov's arc algebra. This modified arc algebra can be thought of as a "disoriented" analogue of the arc algebra, in the sense of the Morrison-Walker disoriented TQFT construction of knot homology. While still preliminary, this result suggests a connection between the Seidel-Smith symplectic knot homology and disoriented Khovanov homology.
