I love it!!!

Here is a much simpler and equally effective script:

In the stone:
onSpawn: _homePos := pos; _homeAngle := angle

In the plane:
onCollide: e.other.pos = e.other._homePos;
e.other.angle = e.other._homeAngle;
e.other.vel = [0.0, 0.0]


By the way, in your version, the tracer does not appear after the first cycle. In mine it does.

Great idea. Thanks. Done.

I remember making a scene like this before

Yes, I remember the Square Wheel Bike scene.

How?

the rolling stones sounds great!

Q: How?
A: The code to make the ground pattern is in the stone.

I've been having a bad day today but this just made it a little bit better.

That's because you were getting stoned.
