this is what I have at the moment - <http://jsfiddle.net/kommandoss/YuRpU/32/>

What I want to do is when a letter is dragged over the empty space it stays in that place and the original position of the letter is blank without affecting the possition of the rest of the letters , any suggestions how I should do this, should I make the empty box a div or is there any other ways, thank you
