not so much simply a wallpaper or something, it's a set of box art and icons to create a custom "intellivision" folder on your desktop.

a massive load of reasonable small to medium sized images to create an "intellivision" folder(s) on your desktop. Ment to run the games from a batch instead to use a GUI and to create your own "GUI" by using simply the graphical capabilities of your OS.
Includes
box images ment as folder icons.
downsized icons for the batch/shortcut.
icons for the manuals (rather simple but straightforward ones).
overlays in a size they can be used wether as, to show off the overlay or to be used as image.

In OSX you can "clamp" them to any file/folder easiest using "FastIcons".

windows offers, i guess since win7 the possibility to take any image as an icon.
