Oyako de Asobo: Miffy no Omocha Bako (Wii, 2010) is a Japan exclusive game for younger players that can communicate with an empty Nintendo DS.
Six different color book pages can be sent to a waiting DS and then colored using colored pencils. When finished, the DS picture can be sent back to the Wii for viewablity on the big screen. Only one DS picture can stored in the WIi game though. It is sort of like Mario Paint-lite as a quick comparison.
