The Scientific-American/Sumeria collaboration is quite beautiful, and intelligently done. This can not be said for avalanche of CD-ROM products currently available. I live and work in this industry (I'm an Instructional Designer), and most developers are only interested in marketing for Xmas. There's a lot of junk out there. For those interested in the process of artistic expression, I can recommend the very high quality of 'American Dreams' produced by Eden Interactive, in SF. Phone # 415-241-1450 Best.
