Missile Command is a 1980 shoot ’em up arcade video game developed and published by Atari, Inc. and later licensed to Sega for Japanese and European releases. It was designed by Dave Theurer, who also designed Atari’s vector graphics game Tempest from the same year. The game was released during the Cold War, and the player uses a trackball to defend six cities from intercontinental ballistic missiles by launching anti-ballistic missiles from three bases.
- Silt (Wikipedia)
Silt is granular material of a size between sand and clay and composed mostly of broken grains of quartz. Silt may occur as a soil (often mixed with sand or clay) or as sediment mixed in suspension with water. Silt usually has a floury feel when dry, and lacks plasticity when wet. Silt can also be felt by the tongue as granular when placed on the front teeth (even when mixed with clay particles).
