One of the best!
For anyone who enjoys kaleidoscopic images, this app would have to be the best value in iTunes. You get the 'traditional' kaleidoscope view (without the inevitable blurring towards the edge of the field of view caused by small imperfections in the mirrors in a physical kaleidoscope) by setting the Kaleidoscope type menu to 'Hex grid'. There are over a dozen inbuilt source images from which to choose (many based on images og sections of the Julia set) and you can load your own images as sources. You can then explore the image by moving the source triangle manually, or by starting 'animation' which causes the source triangle (the size of which is adjustable) to move at a chosen speed and rotation around the chosen image. Seen full screen, with speed and rotation set to low values, the effect is mesmerising and quite the equal of any physical kaleidoscope. In addition to the traditional kaleidoscopic view, using 'Hex grid', you can also choose 'Polygon fan' that displays a polygon of any number of sides from 3 to over 64 in the centre of the screen (segments can be mirror images, or rotational repeats). Eight-way tile patterns and eight-way squares can also be produced and, naturally, the images can all be saved as jpegs. A useful feature that is lacking is the ability to save animations as quicktime files. Maybe this will come in the next version.
