Mock-up Gallery for Displaying Wallpaper

Here’s what I have so far.

Most of the wallpaper I make is in widescreen format, so the vertical menu would not work as well as a horizontal menu.  The question is which technology shall I use.  I can make effects easier with Flash, but if I use Javascript, then I can make it more extendable and automated.  I think in this case, I will try the javascript approach and have some fun playing with visibility.  For selection, I will do a simple border.  It should be a nice exercise.  I will start planning the code tomorrow.
