Abstract: A projectile having photoluminescent properties is exposed to light within a gun when propelled from the gun to excite the photoluminescent surface and provide a visual display by the propelled projectile. The projectile is illuminated by a flash lamp, such as a xenon flash lamp, having a high level ultraviolet light component and relatively low or non-existent red, orange and infrared components.

Abstract: Composing an image from fragments of the image. The fragments of the image and a playing grid (used to define the fragments) are downloaded from a server. The positions of the fragments are shuffled within the grid. The appearance of each fragment is altered to conform to characteristics of the fragment's position or cell within the grid. After displaying an initial configuration of the fragments, one or more fragments are selected and moved to new positions or cells within the grid. In one embodiment, a single fragment is selected and moved to a new cell. In another embodiment, a fragment in one cell is selected. A new cell having another fragment is also selected. The two fragments are swapped between their respective positions or cells. After moving or swapping any fragments, the appearance of a moved or swapped fragment is altered to conform to characteristics (such as the size, shape, and aspect ratio) of the fragment's new position or cell within the grid.
