Follow these steps:
Open a new workbook
Press F5
Enter X97:L97 and press Enter
Press Tab
Press Ctrl+Shift and click the Chart Wizard button on the toolbar.
You'll be greeted with a full-screen animated image. 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
right 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.
