This demo is all about transparency to cause as little obstruction to your image gallery as possible. The whole theme has almost no major distracting colors and instead uses only black for the necessities. Arrows and descriptions are surrounded by curved rectangles and disappear when not in use. They allow you to navigate the pictures quickly and if you need a better look at the image title then you can simply pass the mouse over it to give it a nice green background in case the theme's black coloring doesn't agree with your photo.
There's also little circles at the bottom of the demo that let you keep track of how far along the slide show you are. Passing the mouse over these will make each circle's respective image appear in an appropriately sized rectangle. Due to it's simplicity and focus on lack of obstruction, this theme is fit for any kind of gallery.
The actual slideshow uses the Cube effect. The transition looks like a rotating cube with images on the sides. The slider can rotate in all sides horizontally and vertically. This effect is smooth and looks marvelous.
