A very simple program that chooses one sprite at random from a directory of your own choice (to be set in the !Run file) and uses this sprite to make a tiled backdrop.
(If you use sprites which need to be scaled then you have to alter line 25 in the Basic program. Alter '-tile' into '-scale'.)
Either use this application by simply running it, or set a task-alarm in !Alarm to have it run with any interval of your choice. (My desktop changes every hour in this way.)
BTW: !RandBdrop's icon displays its background. Try this by pinning the application on your screen and doubleclick it....
