With Kaleider 4.8, the Kaleider Screensaver is free!  Also, some fairly major improvements in functionality and memory efficiency.  Further details below:  (Also see Kaleider 4.8.1)

• Free Screensaver =>  The fully functional Kaleider Screensaver is now freeware!  The screensaver is no longer included in the main Kaleider trial download, so existing customers (and everybody else!) please download the latest version from the Kaleider Screensaver page.

• Upscaling =>  The Upscaling process has been entirely revamped to greatly improve the efficiency of memory usage.  This should make it possible to render and save significantly larger images.  Upscaling is also more capable now of handling the most complicated situations, such as 'compound' effects (a sequence of effects on the same image), source image color shifting, etc.

• Right Triangle Funnels =>  A new Right Triangle based Funnel has been added, along with the usual Split variation .  As with other Funnels, the final results can often be greatly improved by rendering with Improved Quality .
  

• Pattern Areas =>  A Pattern can optionally be confined to a specified portion of the window display so that any rendered effects will appear only within that area.  (The full window is still used to display source images.)  For example, the current Pattern Area might be set to a square, framed by black (or some other color).  Masks can be applied within a Pattern Area, a round Mandala within a square Pattern Area for instance.  Options are available to Save and Copy only the current Pattern Area (rather than the full window).  The Pattern Area screen provides options for defining the dimensions, position and functionality of the current Pattern Area.
  

• Minimized Buttons =>  The effect buttons on the Kaleider Tools panel can be 'collapsed' so that only the currently active effect buttons appear under the Kaleids, Mirrors and Funnels labels.  Those labels can be clicked to toggle the collapsed/expanded appearance of the buttons.  When collapsed, the arrow button can be clicked to show the full panel of buttons off to the side so that a different effect can be selected.  This option is meant to better accomodate people who use small screens or who prefer to resize the Kaleider window to a small area.  It perhaps makes it more practical to increase the Interface Scale (in Appearance Options) so that larger text and buttons are displayed.  It also provides more space for possible added effects in the future.  The effect panels will be automatically collapsed when the window is too small to show them in expanded mode.  People with large enough screens might well prefer to continue using the original, expanded style.

• Animate Colors =>  The Animate Colors feature has been greatly expanded and enhanced.  Now there are 5 Colorize Methods:  Garish (essentially the original method), Iridescent, Neonic, Opalescent and Contusive.  The Cycle Type parameter can be set to Switch Colors or Forward/Reverse.  The Animate Colors Options screen has been redesigned to allow interactive experimentation, so that the results of parameter adjustments can be reflected on the main screen in real-time.  The current Color Step can be adjusted via a slider (the slider can also be moved with the Arrow keys or the mouse wheel).  Animate Colors Options can be conveniently accessed by right-clicking the Colors button.

  The Automatic Effects Configuration screen has been revised to add a Colors tab, replacing the old on/off Animate Colors option, making it possible to randomly activate Animate Colors based on a frequency percentage (instead of just always on or always off).
  

• Lost Effects =>  Since the Virtually Tile Source Image option was added several versions ago, it has been very easy to shift an effect tile to a location 'outside of the window' without realizing it -- the program would just make the necessary calculations to retrieve pixels as if the source image were infinitely, seamlessly tiled.  But then if Remake (or the Z key) was used to redisplay the effect outline at its current location, the outline would not be visible, seemingly lost.  Prior to this version, to avoid such awkward, confusing situations, the program would force the effect back onto the screen so that the effect outline would be visible.  Unfortunately, that would cause the shifted-to position to be lost, and the effect would not be recreated exactly as before.  With Kaleider 4.8, a message will be displayed instead to indicate that the effect is outside of the window.  The position can then be adjusted if desired by using the Effect Controls, or a box can be clicked to re-position the effect outline to the center of the screen -- or it's also fine to just re-render the effect at its current, off-screen location.
  

• Other =>  Quite a few miscellaneous enhancements and fixes were made with Kaleider 4.8.  Here are some of the most notable:
  • The rendering algorithms for some of the 3D Mirrors have been improved, especially for Spherical and Ellipsoidal Mirrors.  Upscaling should be more accurate for all 3D Mirrors.
  • The timing for video captures should be more accurate when the Automatically Adjust Capture Timing option is set.  An option has been added to the Video Options screen for Capture Pattern Area Only.
  • All of the Open and Save Dialogs for images and other files have been updated to newer, more capable styles.
  • If an ICC Color Profile is stored within a source image file, then that information will now be retained with any saved Kaleider generated images that were derived from that source image (for JPG, TIFF, PNG and PSD image formats).  Also, the Save / Quick Save Options screen includes a new option to similarly copy and save EXIF data from original source images (again applying to JPG, TIFF, PNG and PSD formats).  The default Save Directory can now automatically be set to the last folder saved to.
  • The Scripting feature has been enhanced to better perform a 'snapshot' capture of the actions needed to recreate the currently displayed effect.  Just press the Script Rec button twice to turn Script Recording on and off.  That would immediately capture the source image used and the effect (or effects) applied, along with the position, size, rotation, scaling, color shifting, etc.  Room, Mask and Surface status would also be captured.  That Recorded Sequence could then be saved as a Script, which could later be played to reproduce the same effect.  A digital artist, for example, might use this capability after an interesting image has been created to store a record of the actions needed to recreate that image.  Potentially, the Script Control and Editing function could then be used to tweak parameter values, or even render with different source images.
