Weird Dream Last Night

So my wife and I have been looking at house plans with the intent of building one day.  And I have been scripting a lot.  I don't know exactly what triggered it but I had a dream we were building the house and I was laying out the floor with CSS and Javascript.  I made it self cleaning.  To bad it can't really be done this way.

<div id="kitchenFloor" class="Pergo Mahogany WideStrips" onwalk="selfClean()"></div>

function selfClean()
{
     var floor = house.getElementById("kitchenFloor");
     if(floor.mud == true)
     {
          //remove Mud
          floor.mud = false;
     }
}
