Masahiro Sakurai's Wife Designed The Menus
A source states, "Series director Masahiro Sakurai enlisted the help of his wife, graphic designer Michiko Sakurai, to work on the Super Smash Bros. games. She specifically designed the user interface, menus, and some of the stages. She continued to design the menus from the original all the way up to Brawl.
Michiko Sakurai has done design work for many other games, including Meteos, Kid Icarus: Uprising, and a handful of Kirby games. She and her husband work on games together often, and her style has since become a trademark of Sakurai's games"(Jacobs).
