Interesting scene, and very well made. Good job!

Question: There are three objects in the scene that I don't know what they do.
1. The thing that looks like a red egg.
2. The large light-gray circle on the left side.
3. The trapezoidal shaped object under the smiling mouth that moves back and forth like a pendulum.

Please explain those things.

The red "egg" beats like a heart, and shows the pendulum frequency as it beats. You can change it by altering scene.my._cardio

The light-gray circle is like a barometer, that feels the pressure inside the organism. It blinks every time a particule hits it, and counts the frequency of beats. In its code, you can change some parameters

The pendulum that goes back and forth is like a pump, that helps keeping the movement inside the cell. As new cells are generated, the kinectic energy tends to go down, so a pump is required. It changes with scene.my._cardio.

The faster the cardio, the easier it is to remove "plaques" (toxin clumps)

Nice work.
