You notice that one of your desk drawers is slightly open. You open it and discover a flat rectangular object. It looks like a diploma, except that it is engraved on a shiny plaque made of an unusual material. Maybe you get a prize for solving so many puzzles? On the plaque, you see a few official-looking congratulations and recognitions, but this phrase stands out:
A Prize That Matters
This plaque is made of a very intriguing material — there’s more to it than meets the eye. There must be a final puzzle to solve!
Note: this final puzzle is independent of all the previous puzzles.
