Here’s my second offering on the useless iphone app front, kaleidoscope. It simply replicates the effect of the toy that ya used to put to your eye as a kid and marvel at changing colours as you twisted the end and watched the coloured sand swirl into different patterns.

To interact with this version ya can either touch the screen and change the patterns or use the accelerometer and turn the screen.

It may seem useless, but for 5 or 6 seconds a day it brings a little colour and a smile into your life.
