Open a new spreadsheet, then go to cell IV16384. (Press Cmd-Right then Cmd-Down to jump there.) Use the scroll bars to scroll down and right more until only that cell is showing, then set that cell's width and height both to 0. All that will remain in your window will be the little square in the upper-left-hand corner that you normally click on to select the entire spreadsheet; click on it.
The contents of the window will be replaced by a little Lotus-stomping then a list of Excel's programmers and beta-testers. When your normal Excel window comes back, scroll away to keep the show from repeating.

Here's another: set the style of any cell to "excel" (by selecting "Format Styles..." and typing "excel" without the quotes). Then choose "About Excel..." from the Apple menu and click on the big Excel icon.
A brief animation ("So good, it hurts.") alternates with the names of the developers ("Recalc or Die!").
