That is just fantastic! I love those images... I've been kicking around something a bit different - a computer screensaver tyope of application that shows a sundial with the current time. The twist is that this is for a mobile application, so the "sundial" image would have to change based on GPS coordinates. I haven't take this beyond the thought experiment stage, though. -- If you have eight hours to chop down a tree spend six sharpening your axe. --Abraham Lincoln -- If you have eight hours to chop down a tree spend six sharpening your axe. --Abraham Lincoln --------------------------------------------------- https://lists.uni-koeln.de/mailman/listinfo/sundial
