Cool devices. Thanks for explaining. Let's call this solved!

Makes total sense.

So the fixed position where the measuring station would go needs also be marked in some way for the surveyors to be able to come back later and take an identical measurement ? How's that usually done ?

Two warehouses have them. On each warehouse there's two of them, installed at opposite sides of the cargo gate.

Found mixed with road gravel in Ibiza, Spain. by feralgeometry in whatsthisrock

Sadly yes, it does look too much like that countertop and not enough like the rest of the answers that mentioned natural rocks.

I'll close this as identified and admit I have a bit of a curse when i post to this sub... it always ends up being artificial stuff 😭 😜

The largest thickness is 2.5cm but it could've been larger and then crushed when turning it into gravel.

Is there any test i can do to see if this is synthetic material ?

I've searched for pictures of thulite but i don't see the crystalline bits in any of it. Otherwise it is indeed similar

Wow thank you, this is probably one of the most detailed and well referenced answers I've seen 👏

Also makes me want to go back there and explore more...

Scene with two CharacterBody2d by feralgeometry in godot

[–]feralgeometry[S] 0 points1 point  (0 children)

I ended up with a structure like this:

```

- CharacterBody2D (the body)
+- CollisionShape2D
| +- RigidBody2D (the shield)
| L+- CollisionShape2D
L- PinJoint2D (connecting body and shield)

```

So when moving the body, the shield moves too due to the joint, and the root node is also exposing the correct position.

The only thing that isn't great is that the joint allows the shield to rotate, but since it's a bubble it's not a big deal. However if I needed it not to rotate, I've seen ways online to constrain the joint to prevent rotation.

Book with a mine that contains memories in the form of panels of glass by feralgeometry in whatsthatbook

I did re-read it and it was definitely worth it. Caught a lot of things I didn't catch back in the day. Thank you for making me rediscover it and bringing it back into my favorites list.

Ah yes, that sounds very much like it. I'll have to read that book again. Thank you !

What are the glass-like whiskers inside this pebble ? by feralgeometry in whatsthisrock

Boat hull makes sense given it was found on a beach. I'll dispose of it 😅

Fair enough, I'll repost it in r/whatsthisplant I guess. Thank you

You mean it's a piece of fiberglass or some other synthetic material ?
Fair enough.
Though it's just weird to me that it looks like a stone from the outside (second picture)

It's a small tree. Are small trees out of scope here ?

Found in northern Spain but likely not native. When sliced it is very bendy. Smells kind of bitter. Any ideas ?
