Your 2nd para:
1. create a new sheet in openoffice.org Calc (spreadsheet)
2. enter this formula in a cell :
=game()
and validate (validation button or enter)
3.the cell will display "say what?"
4. Enter this formula:
=GAME("StarWars")
5. a new window will open with a little game star wars game.
6. But if you type again this formula, the cell will return the display "oh no, not again!"
