Maybe 8 years ago I was paired with this really quiet dude for a group project. It was for statics engineering. We had to create a poster board with force diagrams on cars, bridges, buildings, etc. We needed to create a bunch of drawings and discussed how to create them. This dude just quietly said "I can use paint" and started clicking away.
He opens paint while no one is really paying attention to him. Within 2 minutes, the first drawing was done. We all were confused so we started to watch him work. He was flying through the whole project. He would copy sections, move them slightly over, draw a couple lines, and have immaculate 3D pictures. He single handedly created all our diagrams in 30 minutes. Our group of 5 got an A on the project.
To this day, I still use paint doing some of the tricks I learned watching him work.
