"I thought of this riddle while returning from my college.
I am a proud father , whenever I give birth to one of my children.
My offsprings can cause major mood swings ,
they can satisfy your hunger , and yet they can sometimes frustrate you.
Whenever you scrutinize them you find yourself sucked into another universe , oblivious to the sands of time flowing by.
My children are not humans(as you may have guessed) nor are they anything living."
Can you guess who my children are?????
Now take your time.This may be easy or difficult.It all depends in the direction of your thought.
