Until you see that we really use the file for testing purposes. Originally created in 1995 to kick the tires on the new Microsoft® Products of the day (Microsoft® Office 95, Windows® 95...), we've found that it helps us get a handle on each new release.
The FractalTraveller allows you to explore the Mandelbrot set using translate and zoom in/out actions. The image is not generated using cell formulas, but by assigning each cell a color, as though it is a pixel in the image.
Among other features, you also can name and save the key parameters to recreate an image, change the color palette and create different schemes (rules) for how any color on the palette is used.
Check out the comparison between the image created with Microsoft® Office 2003 vs. the same image created using just some of the added space available in Microsoft® Excel® 2007!
This product is intended for use with Microsoft® Office 2000 and above for Windows®.
Sorry, it doesn't yet work using Microsoft® Office for the Macintosh®.
