Vectrex was an old game console with an integral CRT, famous for the "vector scan" CRT it used. Basically the only new principle involved is that instead of cathode ray beams always scanning on a fixed rectangular pattern, the X and Y deflection amounts were provided by the game to move around the singular dot to desired locations. It's crisp as waving around a laser pointer. Some people like that aesthetics.
