This 2.3 MB GIF animates 10 Cereus pictures at reduced size and in greyscale. The greyscale conversion was done because the original color images looked poor when reduced to 256 colors (as required for GIFs). The image should continue to loop, and (for some reason) looks much better on Netscape and OmniWeb than on Internet Explorer.

Animation transitions were made using Yves Piguet's GifBuilder for the Macintosh.
