Light Painting whoooo!

My Professor in Photography teach us how to make light painting. It is very fun because you can do all you wanted to draw using light.
But what is the meaning of Light painting?
It is a photographic technique in which exposures are made by moving a hand-held light source while taking a long exposure photograph, either to illuminate a subject or to shine a point of light directly at the camera. Light painting can also describe works where the camera itself is moved during exposure.

(Wikipedia :3 ).

At the picture below, this is my light painting that I create using my nickname. :)
