This is my first project in awhile, but although I may seem inactive I am working on 2 games: Xlik and Christmas Blast (both names still debatable.) This is a sine-wave generator with 4 parameters: frequency, amplitude, coloration, and thickness. For a basic sine wave answer 100, 5, 0, and 2. Then you can experiment from there. Frequency is how fast the wave moves up and down, while amplitude is how far from the screen's center the wave will reach, for instance inputting "100" will make it go up and down 100 pixels from the center. I made this in a few minutes at school. Enjoy!
