JQuery Drawing App: Erasing or Refreshing?

I just wrapped up the JQuery "Drawing Application" lesson, is it possible to create a button to refresh just the canvas element, allowing a new image to be drawn?

Theoretically, using a white color would allow you to "erase" the lines, maybe with a script to increase the cursor size? Is that possible?

I answer that here https://teamtreehouse.com/forum/adding-an-erase-button-to-simple-drawing-app-howto

If you want to clear the canvas you can use context.clearRect ( x , y , w , h );
