I don't think I've actually seen anyone talk about this before but a really interesting detail from the Jinx Fixes Everything game is that Silco's office has canvases and paintings all over the floor:
And if you comb back through the show, you can see them in a few of his office scenes as well:
Also among his office props is a book with the Vitruvian Man on the cover, so it could be some sort of anatomy guide??? Which also implies the existence of Leonardo Da Vinci in this universe, but Imagine Dragons are canon too so I guess it's not that insane lmao.
He also has a painting on the wall behind his couch, although there's no evidence to determine whether he painted that himself or purchased it from someone (or stole it). The canvases on the floor definitely look like they're his though. The only people who actually spend long periods in his office are Silco and Jinx, and we know that when Jinx draws, she does it completely out in the open - all over the floor and walls and many of the belongings on Silco's desk. Meanwhile, Silco's canvases are mostly turned around, facing towards the wall. It makes it seem like there's some kind of shame attached to them; like whatever is on them, he doesn't want anyone else to see.
