Thunder! Here is the God of thunder - Thor Odinson from Asgard! Or is it Zeus with his famous lightning bolts in our Blue Lightning cursor pack? Also, you can see it in nature. It is a rare occurrence typically seen during thunderstorms or other electrical storms. Blue lightning is created by the excitation of nitrogen molecules in the Earth's atmosphere, which produces a blue glow. Blue lightning is sometimes seen along with more common white or yellow lightning, but its unique color makes it a striking and memorable sight.
