A platform has a rigid body with an adjustable thickness to selectively occupy any remaining space within a container used for packaging items such as semiconductor wafers. The device intercepts the light emitted by the monitor to produce an abstract, moving display. The interior of the outer cylinder may be moveable between an uncocked position and a cocked position such that movement of the outer cylinder from the cocked position toward the uncocked position compresses air in the interior of the outer cylinder, with the compressed air being delivered to through the fluid passage to a toy projectile attached to the toy projectile launcher.
