A system includes a medium disposed on a base, a plurality of transducers coupled to the base, and a controller communicatively coupled to the plurality of transducers such that each individual transducer of the plurality of transducers is individually addressable by the controller. The controller is configured to receive feedback and to instruct at least some of the individual transducers of the plurality of transducers to activate to move the medium on the base to create a shaped surface based on the feedback.
