hey could somebody help me building a sand shader. looking like sand at the beach..

and i need to fill the treasure chest wid them gold nuckels.. how can i make it not looking sorted..

i tried it wid dynamics to have em fall inside the box but somehow the gold nuckel kept falling throu the geometrie. i had the gold nuckel on "activ rigid body" and the box inlay as an "passive riged body"
and when i tried to have more then one nuckel maya stopt and gave me an error message about two things collided ...
