Use this version
and that on the following page to create the illusion of an interface with buttons
which glow or change shape when touched. Select a button area and copy it as
a separate image; swap that image for the basic image on mouseOver or other
I've rendered the full image for the different states rather than just the button areas in order that all the 3D depth and reflections will be present and correct for each altered state.
reticent version for mouseovers
