Sprite designers chose for transparency and high performance at the cost of residual dependencies and significant complexity in the kernel.
On the other hand, the targeted environment of the Sprite system was a collection of workstations on a LAN (instead of a wider network) and in particular, memebers of the Sprite project.
Sprite makes every attempt to keep the migration transparent to the user and the process, which is an important contribution of this system.

  Sprite (computer graphics) - Wikipedia, the free encyclopedia
Sprites were originally invented as a method of quickly compositing several images together in two-dimensional video games using special hardware.
For each frame the sprites are first bit blited (short for "bit block transfer") into the fast, large, double, and costly frame buffer and then the frame buffer is sent to the screen.
Software sprites were used to refer to subroutines that used bit blitting to accomplish the same goal on systems such as the Atari ST and the Apple II whose graphics hardware had no sprite capability.

 The Mystery Behind Lightning's Puzzling Friend - Science - RedOrbit   (Site not responding. Last check: 2007-09-17)
Sprites, so-named by a University of Alaska scientist inspired by the creatures in Shakespeare's "The Tempest," have been observed since the 1800s, though rarely visible from the ground.
Sprites, like lightning strokes, are largely unpredictable and brief - lasting only 3 to 10 milliseconds and inherently difficult to study.
Sprites and other phenomena, including elves - that bring a millisecond flash of light that fills the entire night sky within a 100 kilometer (62 mile) radius of the associated lightning strike - are generating much interest because of their strong electric fields and electromagnetic pulses that may interact with the Earth's ionosphere and magnetosphere.

 Atmospheric 'sprites' captured in explosive detail
Sprites are fleeting events, which normally last between 10 and 100 milliseconds.
The researchers say sprites typically begin at an altitude of about 50 miles (80 kilometres) in the sky in single spots where the electric field creates a spark.
Based on the new images, the team says "isolated dots" that glow intensely and often outlast the rest of the sprite are the result of a collision of streamers.

Responsibilities Display the sprite (with mouth closed or open in the direction of motion), moves the sprite, animates the sprite motion, and reports whether the sprite is moving.

 LiveScience.com - Secret Sprites: Study Explains High-altitude Flashes
The sprites, as they are known, rise as high as 50 miles into the atmosphere and last only milliseconds, so they are very difficult to study.
Sprites have cousins called elves, which are intense flashes of lightning that can light the night sky within a 62 mile (100 kilometer) radius.
Sprites over thunderstorms in Kansas on Aug. 10, 2000, observed in the mesosphere, with an altitude of 30-55 miles (50-90 kilometers) as a response to powerful lightning discharges from tropospheric thunderstorms.

 Lightning Above the Clouds
Sprites are faint, colorful and exceedingly brief flashes that are now known to erupt high in Earth's atmosphere in a region just below the ionosphere, which begins at an altitude of about 50 miles.
Earlier work also ties each sprite to an unusually strong cloud-to-ground lightning bolt, followed by a second discharge at heights of 25-50 miles.
The lightning and sprite events were linked by their timing and locations, the first being logged by the National Lightning Detection Network, while the sprites were video-imaged by University of Alaska researchers.

 Computer animation Summary
Computer animation capitalizes on a number of principles of human perception in order to trick the viewer into believing that the images seen on a flat, two-dimensional screen are three-dimensional: that is, in addition to height and width, the picture also has depth.
Computer graphics pioneer Matt Elson predicts that in the first half of the twenty-first century, three-dimensional characters will be created that will have the ability to "think" and to interact with their environments.
In 2D computer animation, moving objects are often referred to as “sprites.” A sprite is an image that has a location associated with it.

 SPACE.com -- New Clues to Fleeting Flashes High In the Atmosphere
Previously, sprites were thought to be related only to positive cloud-to-ground lightning, a far less common variety.
Red sprites also have on occasion been preceded by lower-altitude flashes known as elves, which are produced by the widespread heating of the atmosphere, caused by lightning.
Grasping the extent of red sprites, and their physics, could bear on the understanding of upper atmospheric chemistry and even on high-energy particles known to affect satellites.

 Clearest Video of Lightning-Generated 'Sprites' High Above Thunderstorms Captured
Sprites are one of the most common of a number of so-called mesospheric transient luminous events (TLEs) driven by lightning, Cummer said.
Sprites typically last for 10 to 100 milliseconds -- shorter than the blink of a human eye, which takes an average of 300 to 400 milliseconds.
Their transience makes sprites difficult to see with the naked eye, despite their common occurrence in association with certain types of active thunderstorms, the researchers said.

 ScienceDaily: Researchers Capture Unusual Sprite-Like Blue Jet
Science Daily — University Park, Pa. Deep in the Puerto Rican tropical jungle surrounding the Arecibo Observatory, a team of stalwart researchers captured an elusive blue jet on video tape and found the first evidence of a connection between the ionosphere and cloud top in these events.
Sprites usually propagate from 60 down to about 25 miles, are predominantly red and last for only milliseconds.
This is similar to the normal upper terminal altitude of blue jets and the lower terminal altitude of sprites." Whether this is a newly captured atmospheric phenomenon or simply a variation on a blue jet is not yet known.
