  photodrome \pho"to*drome\ (f[=o]"t[-o]*dr[=o]m), n. [Photo- +
     Gr. dramei^n to run.] (Physics)
     An apparatus consisting of a large wheel with spokes, which
     when turning very rapidly is illuminated by momentary flashes
     of light passing through slits in a rotating disk. By
     properly timing the succession of flashes the wheel is made


     to appear to be motionless, or to rotate more or less slowly
     in either direction.
