Are you saying that there aren't? - There is a finite number of possible screen-images, at least from the point of view of the process sending digital signals to the screen. If the monitor refreshes each pixel N times per second, then over an interval of T seconds, if each pixel can show C colors, then there are C^(N*T*800*600) possible different scenes showable on the screen during that time period.... A big number but finite! Drawing on a page is a different story, as it gets into physics questions, but it seems rather likely there is a finite number of pictures on the page that are distinguishable by a human eye. So, whether or not an infinite number of objects exist in the universe, only a finite number of distinctions can be drawn on a monitor (for certain), or by an eye (almost surely) ben g ------------------------------------------- agi Archives: https://www.listbox.com/member/archive/303/=now RSS Feed: https://www.listbox.com/member/archive/rss/303/ Modify Your Subscription: https://www.listbox.com/member/?member_id=8660244&id_secret=114414975-3c8e69 Powered by Listbox: http://www.listbox.com
