• It looks like a bike lane, only narrower.  Check out these BBC pictures of nightmarishly bad design, and try to imagine a car lane being treated the same way.  (Hat tip to Cyburbia.) Any examples from your commute?

• Paper castles and more from Danish artist Peter Callesen, who writes, "I find the materialization of a flat piece of paper into a 3D form as an almost magic process." (Hat tip:  Mental Floss.)

• Woolly math by Pat Ashforth and Steve Plummer, who describe themselves as "designers of mathematical knitwear." The pattern illustrated is supposed to represent four dogs chasing each other around a square field: "The path created by each dog is an equi-angular spiral." It's a bit clearer here. No word on whether sleeping on this cushion would make you dizzy.

• It looks like a president, only smaller. It appears you can actually buy a GWB doll from toypresidents.com.  They seem to be playing it straight, but Bring It On! isn't, offering a selection of humorous non-purchasables, including Mad magazine's "GI Joke" from 2003.
