Don't know if anyone else has mentioned this, but patent 20040029640 describes some very trippy stuff.
Acceleration sensors in all three dimensions being used to control the action.
Some sort of cooking game is described as well.
Some juicy bits:
" This game is to enjoy virtual cooking while moving the portable game apparatus as if it was a frypan or kitchen knife. "
"In the frypan space process, the portable game apparatus is operated just like a frypan to play a game of cooking a fried egg. "
" it is possible to provide the player with a feeling as if he or she adjusts a position to cut the cabbage by controlling the positional relationship between the cabbage and the kitchen knife. "
And my personal favorite:
" Incidentally, in this embodiment, a communication cable 50 is used to communicate between the two portable game apparatuses. However, communication means such as wireless or portable phone may be utilized."
