Excel 97 (Excel 8)

          Excel's 97's easter egg is the most impressive that I've ever seen.
          Follow these steps:
           1. Open a new workbook
           2. Press F5
           3. Enter X97:L97 and press Enter
           4. Press Tab
           5. Press Ctrl+Shift and click the Chart Wizard button on the toolbar.

          You'll be greeted with a full-screen animated image. Use the mouse to
          move around.

          Trigger the egg. You'll be looking at a purple 3D landscape. Use the
          mouse to "fly" over the landscape (the mouse changes direction, left
          button moves forward and left button moves backwards). Fly around a
          bit and you'll see a grey stone pyramid. Fly to the side of the
          pyramid that's black and you'll see the credits scroll by.

          NOTE: If this doesn't work, select the Tools Options command, then
          click the Transition tab. Remove the checkmark from Transition
          navigation keys and click OK. Then try it again.

       Excel 95 (Excel 7)

          Excel's 95's easter egg is quite impressive. To get to it, follow
          these steps:
           1. Open a new workbook
           2. Scroll down and select row 95
           3. Press Tab
           4. Choose the Help / About Microsoft Excel command
           5. Press Ctrl+Shift and click the Tech Support button

          You'll be greeted with a new non-Excel window (fans of Doom will feel
          right at home). Explore the window using the arrow keys and a few
          other keys.

          NOTE: If you haven't seen the photos, you haven't explored the entire
          window! Hint: type excelkfa.

          enough.
