When C1 gets charged the voltage on pin 2 will be high, so the output will be zero, and pin 7 will
be 0V so the capacitor (C1) will discharge, but the LED won't turn OFF, because C3 is charged,
so it will give IB to the base of the transistor and the LED will stay ON, but the capacitor (C3) will
start to get empty so the LED will decrease the brightness.
When C1 gets almost empty, the voltage on pin 2 will be low, so the output will be high, and the
capacitor (C1) will recharge because the voltage on pin 7 is almost 5V, C3 will start to recharge,
the LED will start to light up, and so on.
