The Doodle-Track Car is small enough to fit in the palm of your hand, but it packs hours of entertainment. This small toy car has the amazing ability to follow any dark line, either printed or drawn with a marker or crayon. You can design and print track layouts on the Doodle-Tracker website, or drawn freeform tracks. The Doodle-Tracker Car was named by Popular Science magazine as one of the best toys at the 2010 International Toy Show. It retails for $14.99.
