Casual PWM parallel led lightning

Powered by an AAA 1,5 V battery, this circuit works on an oscillator made with the on/off behavior of the pnp~npn transistors combined with the capacitor in feedback. The big value inductor coil pourpose is to make the magnetic energy trapped in itself collapse through the parallel diodes that, in a second moment (inductor discharge) share an huge current spike (0,1 Amps), while the transistor are "off". 
Like the pulses that modulates the leds are something like random and irregular i used a normally closed button, to make initially start the pulses.

amuses her to say I made the shit! I did not think that an English like you whom I admire door could be so stupid. plus you made interesting circuit! revenge !!!!

The led light is visible?? the current pulse lasts in less than 0,1 ms...
