Mirrored Image Generator is a small web app using HTML5 Canvas and FabicJS to create symmetrical versions of images by duplicating either one vertical/horizontal half or one of four quadrants. Additionally, users can invert the x-axis and y-axis of the mirror sources, allowing for the creation of 32 kinds of different derivative images. The implementation of the canvas is responsive, and the entirety of the symmetrical image fit within your viewport. Users can then export the symmetrical image as a PNG. It's designed to be cross-browser, but if you come across any issues, please let me know.
