Hoverizr is a really small (2.5KB minified) responsive jQuery plugin that outputs manipulated images on top (or below) your targeted images. Currently, it features three effects: grayscale, blur and color inversion. Automatically when you move your mouse over the target elements, the element above fades out to reveal the element beneath whether it is the original image or the manipulated one.Hoverizr takes advantage of the <canvas> element to do all the image processing.
