I am inspired by space, speed, and motion in galaxy. I am interested in creating 3d dimensional space and motion with 2 dimensional lines and colors.
I am interested in allowing people to question the reality. What make one thinks the object is real or not. There are many existing things in our daily spaces that are invisible to our five senses: sight, hearing, touch, smell, taste. Sometimes one can so blinded by one’s thoughts and the reality that the society create. How can one be encouraged to see beyond the curated reality, focusing on seeing and feeling the true forms.
emergence of complexity in sound from fundamental sine and cosine waves, using tools like Houdini, Reason, Nuke, After Effects, and Processing.
