Spegla started as an experiment in mirroring images, sort of how a kaleidoscope works. The idea is basically to have an image and mirror it around a center point to create some interesting symmetries. It eventually grew into this little web application.

There are many ways to manipulate the image. The fundamental controls such as number of reflections, position, rotation and scale are found in the basic view mode. After familiarizing with the basics, try the advanced view mode to get a second blend layer, recurse, video, color correction etc. The randomizer can be used to quickly scramble the parameters.
