The demoscene is a computer art subculture that concentrates in producing demos, which are audio-visual presentations that run in real-time on a computer. The main aim of a demo is to show off artistic, musical, 3D modeling and programming skills. The key difference between a classical animation and a demo is that the display of a demo is worked out in real time, making computing power considerations the major challenge. Demos are generally composed of 3D animations mixed with full screen effects and 2D effects.
The boot block demos of the 1980s, demos that were created to suit within the small first block of the floppy disk that was to be loaded into RAM, were usually created so that software crackers could boast of their achievement before the loading of the game. What began as a type of electronic graffiti or cracked software became an art from unto itself. The demoscene both generated and inspired many methods used by video games and 3D rendering applications today – for example, light bloom, among others.

Democracy is a form of government in which all eligible citizens have an equal say in the decisions that affect their lives. Democracy allows eligible citizens to participate equally either directly or through elected representatives in the proposal, development, and creation of laws. It encompasses social, economic and cultural conditions that enable the free and equal practice of political self-determination. The term originates from the Greek δημοκρατία "rule of the people", which was coined from δῆμος "people" and κράτος "power" in the 5th century BCE to denote the political systems then existing in Greek city-states, notably Athens; the term is an antonym to ἀριστοκρατία "rule of an elite."
While theoretically these definitions are in opposition, in practice the distinction has been blurred historically. The political system of Classical Athens, for example, granted democratic citizenship to an elite class of free men and excluded slaves and women from political participation. In virtually all democratic governments throughout ancient and modern history, democratic citizenship consisted of an elite class until full enfranchisement was won for all adult citizens in most modern democracies through the suffrage movements of the 19th and 20th centuries. The English word dates to the 16th century, from the older Middle French and Middle Latin equivalents.
