The present invention provides a compact liquid crystal optical element for optical modulation and a compact optical device. Cases may be configured to contain a video-capable electronic device and may both protect the device and allow it to maintain a hands-free viewing position. Methods for fabricating the compounds are also provided. Based upon the instructions of the synchronization manager, and without requesting real-time user input, a determination is made whether to copy a file on the one of the at least two portable media devices.
