To reveal the physics behind the acceleration of the universe we need to measure not only the dynamics of dark energy, but explore its persistence and degrees of freedom. Adding to a strong program of cosmological observations, three new probes are developing rapidly. I discuss the prospects from lensing of the cosmic microwave background, strong lensing time delays, and high redshift galaxy cluster abundances.
