This Kaleider image is another variation of the rendered U-L Side Angle pre-defined Diamond Mirror Pattern.  The underlying source image has been 'virtually' shifted to a different position relative to the tile.  This movement happens interactively so that you can see the re-rendered results and decide when the picture suits your taste.  This example also illustrates how Scaling can be used to interactively re-size rendered effect TilesScaling controls have been toggled on (near the bottom-left of the screen), and the slider was used to rescale Tiles to 72% of their original size.  Tile size can be adjusted from 10% to 200%.  An exact Tile size could be specified by entering a Scaled Tile Width value and pressing the Update button.  Just press Reset to restore Tiles to their original scale (100%).
