jQuery rounding <divs>

Hi,
I am looking for some way to round the divs using jQuery. Would be
happy if somebody can point me to a good approach.
Currently, I rounding the divs using the following way:
$("div.round").each(function(){$(this).corner("round");});
where there is a div with class "round" and on document ready i call
the above js code.
Thanks in advance,
-guntas
