The Websanova Scratch Pad is a unique one of a kind plugin that allows you to add a scratching effect to images something similar to scratching a lottery ticket. It is written using canvas so you would need an HTML5 compliant browser to use it but it does support a fallback to display a message to upgrade to a newer browser if the browser does not have canvas support. What’s really cool is that it keeps track of the percentage of area scratched so that you can trigger a callback once a user scratches a certain amount of the surface area.
