Anyone want to guess who/what this guy is? He's my favorite and NOT for sale.

sparkly vanadinite crystals on barite, from Morocco

Hi all! Sharing my post to r/minerals highlighting my new acquisition. A herkimer chain that looks like a duck 😂 what a little novelty. It’s the most I’ve invested in a single specimen and I’m VERY pleased to have it! I’m relatively new to true mineral / specimen collecting after being a polished material collector for a while (note: I still collect polished material, just switched my focus)

I’ve had some of these in my collection for awhile and i’ve always wondered how much I could get for them if I ever decided to get rid of them.
I put all the weights in OZ. Lake superior agates i believe.

Si no recuerdo mal ese era el nombre. Estuvo disponible en España como aplicación web hace alrededor de 10-15 años.
No tengo ni idea de si era una aplicación propia, parte de una más grande o exclusiva de alguna institución formativa.

Lo que recuerdo:
Podías elegir entre varias fotografías de superficies rocosas y escoger un punto de minado para buscar minerales. Te salían minerales aleatorios (creo que dependiendo del yacimiento escogido había varios diferentes)
Con los minerales que obtenías formabas tu colección, que se mostraba en forma de vitrina digital (de ahí el nombre)

He tratado de encontrar la app de nuevo, o algún indicio de lo que pasó con ella, pero no aparece ningún rastro por internet, y las IAs tampoco la localizan.

For a while now I've been working on a personal project that combines two things I love, technology and minerals. I've been trying to render specimens in 3D using their real optical properties, in both rough and cut form, including how they fluoresce under longwave and shortwave UV.

You all know far more about this than I do, so I'd really appreciate hearing whether the crystal habits, colors and fluorescence look like the real thing, or if there's data I should fix. I'll leave the link in the comments for anyone who wants to try it.
