It is so interesting how everyone reads something different into an abstract. If you think that the squares look like little guys, you may think that the little green guy looks sad, and the orange guy has a Salvador Dali moustache!
If you have a more metaphysical view, you could regard the yellow area as the energy that is created when one physical being interacts with another. Or, alternatively, the yellow area could be the inherent commonality between the two beings.
Perhaps you just see the composition as some cheerful colored squares interacting with some playful black squiggles! And that is just fine too! 🙂
