  Engineers have figured out a way to get crystals to form rose and tulip sculptures, each smaller than a strand of hair. The gardens sprout up on a penny dipped in a salt solution. The technique is similar to 3-D printing and could one day be used to make any complex shape.

• Giant Renaissance Food People Descend Upon New York

  Giuseppe Arcimboldo was a 16th-century artist who liked to play with his food, transforming it into the building blocks of many of his fantastical portraits.
