A display or other type device having intrinsic attention attracting properties and eye appeal is provided in the form of a pendulum type device arranged so the pendulum has an arrhythmic movement in time and/or in space and time. The pendulum may be deviated to one side in its oscillations, and/or temporarily halted at the end of some or all of its oscillations, such unexpected deviations in space and/or in time serving to catch and hold the observer's attention or otherwise amuse onlookers. The arrhythmic movements of the pendulum are controlled by electromagnetic means positioned near the end of the oscillation trajectory of the pendulum.
