Clever use of the motor to turn DC to AC !!
So the main use of the motor is to make continuous current into a on-off (rectangular) curve current, right? Sort of this: http://www.electronics-tutorials.ws/waveforms/tim3.gif
Do you think a BUZZER would work too?

Thanks! And yes, that's exactly the purpose of the motor. A buzzer might work, depending on the variety of buzzer. If it's an electromechanical buzzer, such as a relay wired to self-oscillate, as Lectric Wizard describes below, then you could replace the motor with one of those. However, you can also use a transistor oscillator circuit to generate a low-voltage AC pulse to be stepped-up by the transformer.
In the days of tubes, car radios generated their high voltage by running the 12v thru a relay set up so that as it pulls in it opens a set of contacts cutting off its own power. They were called vibratory generators I think. The coil of the relay would output a high voltage pulse as the magnetic field collapsed & this was rectified & stored in a capacitor. No need for a transformer...
Here's one driving a neon.
