HTL - Homology theories in low dimensional topology

I'll say something about the space (really a stable homotopy type, due to Lipshitz-Sarkar) whose cohomology recovers Khovanov cohomology.  I'll tell you why you should care about the Khovanov space if you only care about low-dimensional topology.  I'll talk about one or two generalizations, maybe including work in progress on annular Khovanov cohomology and the Lie ring action on it.  This is all joint work in various combinations with Jones, Orson, and Schuetz.
