Wool stones on SwissMiss.

A slideshow of Santiago Calatrava buildings on the New Yorker site. Is he getting boring or is it just me?
Sculpture based on graphs. For example: "Consumer Confidence, 2006-07, brass, wood." A cute intersection of art and statistics via Gulfstream.
A public sculpture slideshow showing some nice work by Koons and Anish Kapoor on the NY Times site.
At Shapeways we have quite a few community members working on printing out their avatars. Artist Marc Owens ups the ante by making a life sized avatar-like suit. The suit was initiated because of this fun statistic, "54 percent of all males and 68 percent of all females "gender swap"--or create online personas of their opposite sex." This suit will allow you to do this in real life. Marc Owens does lots of other interesting stuff on the cusp of virtual worlds and art and he's a sure-fire guy to watch.
