Random kaleidoscopic mirroring effects can be rendered and then shifted around the screen, either automatically or manually.  Auto Effects can be activated to continuously generate effects in random motion.  The visuals can be accompanied by music with the built-in Music Player, which can play audio files stored on the Android TV device.

NOTE:  Google Play has suspended the Kaleider TV app, because they say it violates their 'Repetitive Content' policy.  I tried to appeal that decision, explaining that the interfaces of my 2 apps are entirely different.  Since the Kaleider app is designed for touch-screen devices, like phones and tablets, while Kaleider TV is operated by a TV-style remote control, there are very good reasons to offer 2 seperate apps.  But such arguments were ignored, and my appeal was denied.  The APK for Kaleider TV can still be downloaded directly below.  I apologize for the inconvenience.

The primary features of Kaleider TV are briefly summarized below:

• Effects =>  Instantly generate a random effect, or use Options choose a particular effect from among the 203 available varieties (12 Kaleidoscopes, 41 Rectangle Mirrors, 33 Diamond Mirrors, 44 Right Triangle Mirrors, 46 Equilateral Triangle Mirrors, 11 3D Mirrors and 16 Funnels). 

• Wander Effects =>  Wander can be activated to apply continuous automated motion to effects.

• Shift Effects =>  The Arrow keys can be used to Shift Effects to different positions within the source image.

• 3D Rooms =>  Exhibits patterns in 3D perspectives, covering the walls, ceilings and floors of various Rooms.  The Rooms can be navigated via keyboard commands, or automated Roaming motion can be activated.

• Non-Flat Surfaces =>  Maps effect tiles onto a variety of curved Surfaces, resulting in non-linear distortions of the patterns.

• Colors =>  Progressively shifts the colors of effect pixels according to selectable methods.

• Auto Effects =>  Continuously generates random effects, periodically changing the source image.  Wandering motions, Rooms and Surfaces and Colors might also be randomly activated depending upon configured options.

• Music Player =>  Kaleider TV effects can optionally be accompanied by music chosen from the audio files stored on your device.

• Options =>  Buttons are available to quickly perform most actions.  The appearance of buttons can be toggled off to allow more screen area for displaying effects.  Settings can be configured to control Appearance, Colors, Rooms, Surfaces and Auto Effects.

HINT:  If you notice a gap between the Kaleider TV controls and the edges of your TV screen, that is known as an 'Overscan Margin'.  Some TVs need such a border to avoid chopping off parts of the picture.  Other TVs automatically compensate and don't need the borders.  You can remove the gaps by unchecking the Use Overscan Margins option in Appearance Options .  (The change will take affect the next time you run Kaleider TV.)

Kaleider TV Version History

Version 3.1
• The app has been updated to comply with the most recent Android release, Version 14.0 (UpsideDown Cake - API Level 34).
• The C code for the Kaleider App has been reworked, and compiled with the latest Android NDK.
• Control of the Tile Zooming option has been fixed.
• Various other improvements and fixes.

Version 3.0
• A new category of effects has been added:  Equilateral Triangle Mirrors, which are rendered within an equilateral triangle shape.  46 varieties of these new Mirrors are available, some of which produce rather radical results.
• The app has been updated to comply with the most recent Android release, Version 13.0 (Tiramisu - API Level 33).
• Numerous other improvements and fixes.

Versions 2.0, 2.0.1 and 2.0.2
• Numerous updates were made to comply with the most recent Android OS versions.  Also the Java code has been converted to the more reliable and efficient Kotlin programming language.
• Extensive changes were made to minimize the possibility that the app will crash.
• 2.0.1 fixed more glitches that could cause crashes.
• 2.0.2 includes a major fix that should prevent most crashes.

Versions 1.9, 1.9.1 and 1.9.2
• The effect rendering routines have been entirely rewritten to enhance efficiency.  The app now uses less memory, and performance should be somewhat faster and more reliable on most devices.
• The 7 controller button can now be clicked to toggle between showing the full panel of controls, the minimal panel of controls and no controls.
• 1.9.1 fixed a glitch with scaling equilateral triangle based Kaleidoscopes and Funnels (anomalous streaks would appear).
• 1.9.2 corrected a screen resource that was missing with version 1.9.1.

Versions 1.8 and 1.8.2
• The Image Selection process now includes a Select Gallery Album option, which provides a list of Gallery folders to choose from.  Also, the Select Directory option has hopefully been made more efficient by excluding most images that wouldn't be appropriate for use by Kaleider TV (such as icons, thumbnails, buttons, etc).
• Now, when an image is chosen using the Gallery app, the Album that the image belongs to will become the current Image Source for the Kaleider TV app.  The Arrow buttons can be used to page back and forth through the images within that Album.  This should apply both when an image is shared to Kaleider TV from the Gallery app, or when the Gallery app is called from Kaleider TV.
• An Include Bubbles option has been added to Room Options.  That option can be un-checked to remove floating Bubbles from the 3D Rooms.
• 1.8.2 tightened up error checking to hopefully avoid crashes that could occur in some situations.  Also, a Privacy Policy has been included, which can be displayed from the app's Help function.

Versions 1.7, 1.7.1 and 1.7.2
• The Triangle Mirrors feature that was recently added to the Kaleider Windows program (see Kaleider 5.3) has now been included with the Kaleider TV Android app.  A large selection of Triangle Mirror Patterns are available, with 4 variations of each Pattern type to allow a choice of the desired orientation for the right triangle shape.  For example, choose the L/R version for a right triangle with the 90 degree angle at the Lower/Right.  Most Triangle Mirrors are perfectly symmetrical, and often quite intricate.
• Extensive internal restructuring to make the app more reliable and efficient, especially for 64-bit devices.
• 1.7.1 fixed crashes that occurred with some devices (my apologies!).
• 1.7.2 included several additional fixes and tweaks.

Versions 1.6, 1.6.1 and 1.6.2
• More fixes and minor tweaks.

Version 1.5
• This version is also primarily intended to fix occasional crashes.

Version 1.4
• This version of Kaleider TV is primarily intended to improve performance and to fix several bugs.

Version 1.2
• Besides random effects, it's now possible to select and render particular effects.
• Added 3D Rooms and Non-Flat Surfaces.
• The interface has been redesigned.  The Actions Buttons panel is now transparent by default, and it overlays the displayed image, making the entire screen available for exhibiting rendered effects.  (Appearance Options can be used to make the Action Buttons panel a solid color.)
• The Image Selection process has been improved.  The icon can be long-touched to allow selection of an image from the Gallery (or some other image app), and there is also a Use Gallery App option in the Image Selection screen.  The SD cards on most devices will now be detected when selecting an Image Directory or a Music Directory.
• A Motion Control feature has been added to allow adjustment of the speed and smoothness of automated Wandering and Room Roaming actions.

Version 1.1
• The most common functions can now be conveniently performed using the remote control numeric buttons (Use and Actions to show these):
  • 1 = Previous Image
  • 2 = Next Image
  • 3 = Random Effects
  • 4 = Toggle Center Effects
  • 5 = Toggle Wander Effects
  • 6 = Toggle Colors
  • 7 = Hide/Show Buttons
  • 8 = Toggle Music Player
  • 9 = Start Music/Next Music
  • 0 = Pause/Resume Action
• The sizing and positioning of effects has been improved to better adjust to different screen sizes.
• Now, when an Image Directory is selected, only directories that contain images will be listed, along with counts of the images stored within.
• An Audio Directory can also now be selected from a list of directories that contain audio files.  A particular song within a directory can be chosen and played.

Version 1.0
• Initial release.
