For my final project, I am making an electronic beating heart with a heart rate simulator. This is a unique way to show your feelings towards someone that you are into, by beaming the lights according to your heart rate. When you hold the figure in your hands, the lights shine and show how nervous you are when standing in front of someone that you have always been longing for.
