Abstract: A system for performing user-initiated content modification includes a computing platform having processing hardware and a system memory storing a software code. The processing hardware is configured to execute the software code to receive a request to perform a modification to content, determine, in response to the request, whether the modification is permissible or impermissible, and when the modification is determined to be impermissible, deny the request. When the modification is determined to be permissible, the processing hardware is configured to further execute the software code to obtain the content, obtain or produce alternate content for use in modifying the content per the request, and perform the modification to the content, using the alternate content, to provide modified content.

Abstract: A portable solar concentrator includes a stand, a plurality of inner panels supported by the stand, and a plurality of outer panels attached to the inner panels. The inner panels have a reflective surface, and are configured to direct solar energy at a target. The outer panels have a reflective surface and can be configured in an active position to direct solar energy at the target, and can be configured in an inactive position to direct solar energy away from the target.
