A plastic safety closure with a tamper-indicating band is described. A first video signal and a second video signal delayed by a predetermined field are received, a first motion detection result is output when a signal level of the first video signal is greater than that of the second video signal, and a second motion detection result is output if the second video signal is greater than the first video signal. In response to a selection of an item, a prioritized order of the tangible media corresponding to the selected item is provided. In some embodiments, the stereoimages are kept independent and separately directed through differential polarization. Additional information may be displayed in a further display fields, including textual information.
