Seeing the plain walls of his office with every day, Ben Brucker got bored with it. Subsequently, he thought of converting the walls into a collection of amazing superhero murals using post-it notes. When Ben approached his boss with his creative idea; his boss also supported him and sanctioned a $300 budget for the decoration. So, they started the job and it took a full day and 8024 notes. Brucker told Reditt that as they were scheduled to move to another office shortly, he used the non-permanent type post-it notes for decoration.
