This took longer than I thought it would. It is a marble going down a run that looks 3D.
you can use this in your own scenes, just give me credit please.

All you need to do is get a box and add the script to that box and it looks 3d, after a certain distance from the camera it stops working to reduce lag.

I hope you like it. Thank you for looking at this.

here's the script:
r = math.vec.dist(scene.camera.pan, pos);
c = math.atan2(scene.camera.pan(1) - pos(1), scene.camera.pan(0) - pos(0));
r < 50 ? {
for(10, (i)=>{
Scene.addBox({
size := e.this.size;
color := e.this.color;
density := ∞;
pos := pos + ([math.cos(c + math.pi), math.sin(c + math.pi)] * i) / 200 * r;
timeToLive := 0.05;
collideset := 0;
drawborder := true;
angle := angle
})
})
} : {}
