Pixel art involves creating raster images that can be edited pixel by pixel, often found in 2D videogames and on mobile devices. Concept art in games can be abstract or expressive to convey feel and style, rather than just realistic. Textures are used to make game characters and objects appear more realistic, though this effect is different for games like Minecraft. Background graphics, also called themes, are images displayed on a monitor. Print media art involves transferring ink from a matrix or screen to paper, and is used for game packaging artwork.
