Hey there. Could anyone explain to me how this circuit works? I am new to this and I have tried to figure this one out for a while but I can´t seem to understand it. Looks very complex but maybe it isnt? Anyway here is a picture of it. ->

It's a very simple circuit, google 'astable multivibrator' to find out all about it.

This is essentially the same as the "first of two" astable multivibrator circuits that you posted on the other forum.

Only difference with this second circuit, is that there are two LEDs in parallel on each side, so two LEDs will light up at a time.

This astable oscillator has the polarity of the two capacitors shown backwards.
