Information:  - Cybersphere is a `` ball and paddle '' game similar to Arkanoid . The game and its sequel ( Cybersphere Plus ) have recently been released as freeware by the designer . It was designed by Clay Hellman and published by Psycon Software . Cybersphere uses OPL3 FM sound synthesis chip and therefore may require a use of an emulator such as DOSBox for the audio to work .  - Proprietary software is computer software for which the software's publisher or another person retains intellectual property rightsusually copyright of the source code, but sometimes patent rights.  - Overview. The player controls the "Vaus", a space vessel that acts as the game's "paddle" which prevents a ball from falling from the playing field, attempting to bounce it against a number of bricks. The ball striking a brick causes the brick to disappear. When all the bricks are gone, the player goes to the next level, where another pattern of bricks appears. There are a number of variations (bricks that have to be hit multiple times, flying enemy ships, etc.) and power-up capsules to enhance the Vaus (expand the Vaus, multiply the number of balls, equip a laser cannon, break directly to the next level, etc.), but the gameplay remains the same.  - Freeware is proprietary software that is available for use at no monetary cost. In other words, freeware may be used without payment but may usually not be modified, re-distributed or reverse-engineered without the author's permission. Two historic examples of freeware include Skype and Adobe Acrobat Reader.  - Skype is an application that provides video chat and voice call services. Users may exchange such digital documents as images, text, video and any other, and may transmit both text and video messages. Skype allows the creation of video conference calls.  - A ball is a round object (usually spherical but sometimes ovoid) with various uses. It is used in ball games, where the play of the game follows the state of the ball as it is hit, kicked or thrown by players. Balls can also be used for simpler activities, such as catch, marbles and juggling. Balls made from hard-wearing materials are used in engineering applications to provide very low friction bearings, known as ball bearings. Black-powder weapons use stone and metal balls as projectiles.  - A brick is building material used to make walls, pavements and other elements in masonry construction. Traditionally, the term brick referred to a unit composed of clay, but it is now used to denote any rectangular units laid in mortar. A brick can be composed of clay-bearing soil, sand, and lime, or concrete materials. Bricks are produced in numerous classes, types, materials, and sizes which vary with region and time period, and are produced in bulk quantities. Two basic categories of bricks are "fired" and "non-fired" bricks.  - A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation". The first laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light "coherently". Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography. Spatial coherence also allows a laser beam to stay narrow over great distances (collimation), enabling applications such as laser pointers. Lasers can also have high temporal coherence, which allows them to emit light with a very narrow spectrum, i.e., they can emit a single color of light. Temporal coherence can be used to produce pulses of light as short as a femtosecond.  - In video games, power-ups are objects that instantly benefit or add extra abilities to the game character as a game mechanic. This is in contrast to an item, which may or may not have a benefit and can be used at a time chosen by the player. Although often collected directly through touch, power-ups can sometimes only be gained by collecting several related items, such as the floating letters of the word 'EXTEND' in "Bubble Bobble". Well known examples of power-ups that have entered popular culture include the power pellets from "Pac-Man" (regarded as the first power-up) and the Super Mushroom from "Super Mario Bros.", which ranked first in UGO Networks' "Top 11 Video Game Powerups".    What is the relationship between 'cybersphere' and 'video game'?
