Examples [here](https://www.etsy.com/uk/listing/1098735314/), [and here](https://www.etsy.com/uk/listing/1214005801/), or even [here](https://www.etsy.com/uk/listing/923648395/). Sorry I can only find paperweight examples of this, where you can see that the object looks like it’s actually inside the glass.
To be clear, I don’t mean the ones where a **flat** image is engraved, but the ones where it looks like the object itself is inside the glass cube or rectangle!! Where you turn it and you can see all the different perspectives on the thing. I used to have one of these as a kid with an elephant inside, and it fascinates me how you could see it from underneath and all as though it were actually in the glass. I don’t understand how engraving works at all, but especially not like this in such a 3d way. Please help me understand if you can!

They use lasers to sort of damage specific spots inside the glass.
They basically focus the lasers so that only specific spots are getting enough laser to damage the glass.
And because glass is clear those spots can be *inside* the glass.
It actually is a 3D image burned inside the glass.
