EarDraw is a web application that allows you to customize and visualize a human ear shape. Use the sliders to adjust parameters such as ear length, ear width, lobule size, and helix curvature. You can generate random ear shapes, save your custom design, load a saved shape, and even download your creation as an image. Experiment with different settings and explore the detailed anatomy of the ear including the tragus, antihelix, and concha.
