Time domain astronomy offers the possibilty of news lensing searches. By looking for dramatic proper motions, measureable changes in them, or correlations between them, we can infer or constrain the presence of dark objects in our halo, such as black holes, subhalos, or other exotic objects. We consider new search strategies and the possibilities for current and future experiments.
