The Stasi at the fall of the GDR (East Germany) began to destroy all their files on the surveillance of their citizens. Five years following the fall of the GDR, 40 individuals came together to begin piecing the "puzzle" together. People continue to work until this day, just not in the same numbers. Mathematically speaking, this project will take longer than 400 years to finish.

After the fall of the Berlin Wall, officials in the former East Germany did everything they could to destroy documents. But modern technology could now help piece together the puzzle.
