Excellent idea! The region my party is in now is loaded with giant spiders. This will add to the experience.
While not odd, I've been using my 3d printer and color change filament to make some minis to show 'magical' stones, fountains, caves.
I do have a Dice Jail, Dice Dunce cap, and Plinth of Honour. Then the dice just aren't rolling well, the player can opt to shame their dice with the dunce cap and if it persists, they can threaten to throw the dice into dice jail. At the end of the session, the dice that rolled well are placed on the Plinth of Honour.
