Actually the dice are in their own layer on top of the canvas... at least I think it only holds the dice: #editor-wrapper #tdviewport { scale: 2.0; } I'm not sure how to stop the dice rolling off the screen though. Height and width don't seem to behave the way you would expect. You can have a play with these and see if you get anywhere: top: 0px; bottom: 0px; height: 1244px; width: 1244px; padding and border settings might also achieve something, not sure.
