Tired of staring at the same old, same old website all day long? Presuming, of course, that is part of your work. If so, and if you use a Mac, you might want to give this hack a spin.

It will turn any web page you set it on into a Mario level, which you can then use to while the hours away by playing until all the bricks are gone.
