Layered #2

Layered is an exploration into the possibilities of user interaction in creating a personally aesthetically pleasing artwork.
The image is composed of 10 layers which can be reordered, either randomly or in a considered way with keystrokes. Each generated work is capable of being reordered into thousands of combinations, although with some layers being hidden by others the number of visually unique and pleasing combinations is much lower.

's' to scramble the layers
'r' to reset to original
'u' to send the front layer to the back (a bit like undo)
't' to temporarily rotate the image 180 degrees undo with 'y'

Bring layers to the front as follows:
'1' blank solid layer
'2' and '3' textures
'4' '5' '6' and '7' stripes and waves
'8' and '9' circles
'0' border

'h' to generate a 4200 x 3000 version of the current image
'm' to generate a 1918 x 1370 version of the current image
'l' to generate a version of the current image fitted to screen size
'v' to save the current image as a .png
