Believe it or not, but the center orange dot does not change size.
The Cloud is an interactive lamp and speaker system, designed to mimic a thundercloud in both appearance and entertainment. Using motion sensors the cloud detects a your presence and creates a unique lightning and thunder show dictated by your movement. The system features a powerful speaker system from which the user can stream music via any Bluetooth compatible device. Using color-changing lights the cloud is able to adapt to the desired lighting color and brightness. The cloud also has alternative modes such as a nightlight and music reactive mode. See the animation below for an up close look at The Cloud.

Notice how the animation seems to rotate when you first observe it. But if you look at each individual dot, you find that they only move back and forth in a straight line.
While staring at the image, it should appear as you are traveling towards the planet.
