Adorning video-display terminals with eye-popping images, the screen savers of not-for-profit Second Nature Software, in Portland, Oreg., generate support for environmental organizations. Founder Michael Brown contributes all profits (or 10% of sales, whichever is greater) to groups such as the Nature Conservancy, the recipient of $37,000 last year.

The packages include paintings by Monet and Renoir, and photos of animals, mountains, and parks. The collections are sold at retail or direct (800-782-7000) for $15 each and require an IBM-type computer, 256-color VGA monitor, and Windows.
