My senior year of high school I worked on a senior capstone project.
I was very excited about playing guitar and programming in macromedia flash at the time, so for my project, I made a guitar tablature player and creator in Macromedia flash.
The player streamed guitar fingering and song lyrics across the screen horizontally,
synced to the music. I applied for and was granted a copyright for the program.
See below for screenshots of the program in action:
