Abstract
Intensified light emitting diodes intermittently energized while in motion, the light emission thereof being sensed by eyesight retention as dots and bars of light dynamically related and intermixed relative one to the other in an infinite number of geometric patterns dependent upon the simple and compound application of rectilinear, arcuate and rotary motion in combination with the frequency, spacing and duration of pulse application by a flasher circuit modified by adjustment both manually and automatically.

A dynamic display device for intensified illumination with a light emitting diode when in motion, and including in combination;
- a battery power supply comprised of at least one cell producing a voltage,
- a flasher circuit means for intermittent oscillator capacitance discharge of and producing a spaced pulse/waveform at maximum light emitting diode operating voltage and extended duration,
