A little demo I created to demonstrate the z ordering in IGE. 2081 sprites ordered in one display without any further display list branching to have a raw, unfiltered z axis ordering. The farther away from the camera the images are, the more transparent they become. Nothing fancy but creates a nice effect.
The animated version of the image above is only a fifth of the actual frame rate - the demo itself runs of course way smoother.
