Bouncing with an attempt at decay, driven by four numbers in a Custom Tool (put this in the 'Centre X Y of a Transform for example)

Point((time*CustomTool1.NumberIn3), abs(sin(time*CustomTool1.NumberIn1)*(CustomTool1.NumberIn2/(CustomTool1.NumberIn4*time))) +CustomTool1.NumberIn5)

Custom Tool set up like this;

---

Counter for frame number is just

time

Counter for seconds is

math.floor(time/24)

Counter for frames after any second is

---

Drive the Opacity of an ImagePlane with the distance from a camera

min(((Camera3D1.Transform3DOp.Translate.Z)-(ImagePlane3D1.Transform3DOp.Translate.Z)-CustomTool1.NumberIn1),1)

You could just use the number 2 instead of 'CustomTool1.NumberIn1'
