Before each Christmas, the makers of the best toys of the year have always sent the toy's design blueprints to the North Pole. Santa and his elves then use these blueprints to make enough toys for all the children of the world. These blueprints have always been sent by regular mail. This year, however, has seen a significant change at the North Pole, as Santa has just started receiving toy blueprints by email. With three days to go until Christmas Eve, he and his elves sit around the North Pole computer.
