When I think of not busy...it's the fabric and not necessrily the pattern, try one in marbles or batiks. I did one for my husband...he said definitely NO FLOWERS so I used marbles and batiks and he loves it (or he says he does, he's a smart man LOL)! I used half square triangles and just kind of drew out a ohio star for the center surrounded by chevrons...you know, more of a guy looking quilt, I also used earth tones which kept it from being busy.
