Log of Anomalous Items, inside a storage room
How about a storage room, filled with alot of anomalous items from the page "Log Of Anomalous Items" http://www.scp-wiki.net/log-of-anomalous-items
The items has no use in the actual game as a way for the player to advance or too escape the facility easier. But is more of a safe zone, where the player get to enjoy different items that do different things, that weren't too dangerous to be classified as an SCP. It much like the "Paper dragon SCP" where it is just there for show, with small animations or sounds and maybe some sort of display that describes the item and what it does.
Any other notes:
It would be a fun aspect to implement to the game, as there is not alot of people that have done this before.
