I think that we should be able to buy plaques to put on the wall. Like the trophies but also so they don't have a name and date maybe. They'd be like a posh permanent sticky, perfect for putting over teleporters in places like schools. Or they could just be used as trophies like i said before.

And maybe they could be in different shapes aswell.
It's just a thought
