We discuss a new type of deformable mirror made from nanoengineered reflective layers deposited onto liquids. The surfaces are shaped by heating with a laser. The response times of the deformed surfaces are slow (>1 s). Simplicity and low cost appear to be the main advantages of thermally deformable liquid mirrors.
