Something very interesting has come up this week. Vladimir Carrer has created a very simple CSS framework that can even work in IE 5.5.

.dp50 {width:50%; float:left; display: inline; *margin-right:-1px; }

This is of course very limited as you can only use 1,2,4,8,16 columns system. This is a technical demo and should not really be used in production but it reminds me of the CSS power, pretty ingenious.
