The guys over at Making Toys have decided to roll Katamari gameplay up another level by introducing their two player remote control version of the game. On the Site you can find out how the idea came to pass as well as the making of pictures also from the site here's the directions for game play:

Two players are needed
to play the game. Players can choose Shikao or Ichigo to represent themselves in order to start the game. On the floor
there are some objects such as sushi, pencils, ducks, eggs, and so on. Players will race to collect as many objects as
possible with their Katamari balls. When the cars move, the Katamari balls will roll up random objects from the floor.
The player who collects the most objects wins the game!!!!
