Transparency is one technique used to make more interesting presentations.
Unlike RealPix Trix 4, the transparent images I use here will be stills. Transparency will allow me to layer my animations and title images without destroying previously displayed images in the sequence. It will also offer some file size savings over replacing the entire image. To make the interface lively, I will also insert a four-frame animated GIF of a flying plane. Once told to animate, the propellers on this plane will continue to turn until the RealPlayer time-line ends.
