I have posted to net.sources.mac a copy of yet another Idle desk accessory.
The features of this one are:
o erases the whole screen and randomly moves an icon around
o runs during the host application's idle time (ie., does not take over
the whole machine)
o exits when you press the mouse button (so long as the cursor is not in
the menu bar) or if another window becomes active (ie., if you are in
the Finder and insert a disk)
o if you hold down the Option key you can see what used to be on the
screen (it does not save the bits, however, so it relys on the
application being able to respond to update events)
If you examine the driver you will find the charaters ICN# followed by a
word containing 3. This is the resource type and ID of the icon that it
flashes on the screen. You can edit these to customize your desk
accessory. (For example, display a different icon depending on what
application is running. If you do this you would want to install the
driver in the application itself, including the Finder.) Both ICON and
ICN# resource types will work. If the resource does not exist a square is
moved around instead.
Implementation Note:
The DA creates a window the size of the screen. It copies the window's
portRect into its visRgn before drawing, so that it can draw on top of the
menu bar. It saves the old menu bar and clears the menus to ensure that
the user cannot pull down a menu. When you hold down the option key it
repaints the menu bar and shrinks the window down to 0-size.
You can distribute this freely, as long the credit (blame) is properly
attributed. Report comments/bugs to me.
Enjoy.
