Lines: 48 This is a completely unhelpful reply -- but it confirms that nature sometimes mimics fiction.

The integration of >o.d.e.s is easy, the translation into sound is not. There is a character in Douglas Adams' book "Dirk Gently's Holistic Detective Agency" whose current project is to write an all-singing, all-dancing Macintosh spreadsheet program "... And being of a slightly whimsical turn of mind I took him literally." "... So I sat down and wrote a program that'll take those numbers and do what you like with them. If you want a bar graph it'll do them as a bar graph, if you want a pie chart or scatter graph it'll do them as a pie chart or scatter graph. If you want dancing girls jumping out of the pie chart in order to distract attention from the figures the pie chart actually represents, then the program will do that as well. Or you can turn your figures into, for instance, a flock of seagulls, and the formation they fly in and the way in which the wings of each gull beat will be determined by the performance of each division of your company. Great for producing animated corporate logos that actually *mean* something." "But the silliest feature of all was that if you wanted you company accounts represented as a piece of music, it could do that as well. Well, I thought it was silly. The corporate world went bananas over it." "... Not so much here. The yearly accounts of most British companies emerged sounding like the Dead March from Saul, but in Japan they went for it like a pack of rats. It produced lots of cheery company anthems that started well, but if you were going to criticise you'd probably say that they tended to get a bit loud and squeaky at the end." This has nothing to do with the rest of the book (which is described on the cover as a Ghost-Horror-Detective-Whodunit-Time-Travel-Romantic-Musical-Comedy Epic), but I am waiting for such a product to actually be released [perhaps on the NeXT box ?] :-) [Quotations from "Dirk Gently's Holistic Detective Agency" by Douglas Adams (re: Hitchhiker's Guide to the Galaxy), Heinemann.
