I'm assuming OP is the author:

very nice idea, very nice execution. Few things that imho need to be fixed (probably fast fixes): 1) Ensure that the print settings are correct. i.e. the pattern get splitted on two pages, for no reason. 2) resizing the browser window stretches/squeezes the picture. You shoud probably listen to the resize events and re-trigger the generation, change the patterns to some css, or simply set the generated image as cover. 3) translate the code in english. In softwares, having standards is a good thing.
