the pictures in that thread look pretty impressive to me... Because light hits objects as they would in the real world the scene looks "real". Just google it a bit more, theres some pretty basic pictures out there which show the idea and then there are full on ones that give examples such as lotro etc.
Pic look good but at the same time it looks very dead.
