All these illustrations were created out of nothing on a Macintosh. (except for the image on the label of the diskette which was made by an unknown artist some time before there was a Macintosh)
On an eight bit monitor (256 colors) you will loose a lot of the color nuances in the images.
These images are not optimised for the 256 netscape colors because I wanted to have the best quality for viewing on a 24 bit monitor.*)
Tecnical details on how to obtain the maximun color quality on the WWW will be on a WEB-site I'm preparing on the server of the Institute of Astrophisics in Pisa, a site kindly offered by Prof. Bruno Barsella for educational purpose.
*) The rest of this site is optimised for 256 colors and I hope you can appreciate the color quality of this site.
