The image bank itself can be searched and browsed by theme, timeline, or style. The image previews are zoomable, though within a frustratingly small window.
The animation, however, is larger. In it the creators (for whom I couldn’t find credits) have taken a number of wonderful Flemish paintings and, with considerable computer artistry, separated parts of them into planes, filling out areas where one plane was in front of another.
The result is an animated view of the works, and wonderfully handled transitions between them, that I cannot adequately describe, or show with the static screenshots above.
You simply have to see the animation to appreciate its visual charm.
