Active

1. The complementary colors are bright and exciting,

2. The word "active" in the background is blurred and curved so it looks like its moving,

3. The letters are of different sizes and orientation to provide a sense of depth, like the letters are falling from various places at various speeds,

4. The falling letters keep your eye actively moving around the page because they lead your eye through it, and

5. The whole piece feels like it is a snapshot of a very active scene where the letters are all over the place, falling from above and going off the page on every side.
