This Kaleider screen shot displays a photo after the Bottom Corner Triangle pre-defined Diamond Mirror Pattern has been selected.  The Mirrors have been created within a diamond shaped 'Mirror Box' that has been adjusted to the desired size, and positioned on the screen with the mouse.  (Exact position and size values can also be set via the Effect Controls panel at the top of the screen.)  The Mirror surfaces (in this case 3 of them) are outlined, with the red lines representing the 'plane of reflection' for each Mirror.  The Kaleid Tools panel along the right edge of the screen contains buttons for most of the common options and Kaleider effects.  Edit Tools along the bottom of the screen provide controls for manipulating images and Tiles.  Both of these can be toggled on/off via keyboard commands.  A Popup Menu is also available to access all Kaleider commands.  Just press Render (or the Space Bar) to render an effect.  The Shifting Effects feature can then be used to reposition the result as desired with the mouse, essentially re-rendering the same effect based on different relative positions within the source image.
Kaleider Screen - Mirrors Created
The Appearance Options function allows you to set preferences for the interface.  This sample screen shows the Standard Windows Interface Style, with mostly black text on a light background.  Click here to switch to the Kaleider Original Interface Style.  The interface can also be scaled to a larger size, perhaps making it easier to read text and buttons on large, high-resolution monitors.
