You can drag the purple point, use Re and Im Slider or use the arrow keys to set the point location. This helps you understand complex math.
This project was inspired at Alan Becker's Animation vs Math. Radiants Formula: Rad = (π/180)*deg Gradiants Formula: Gra = (10/9)*deg Sorry if I was lame because I don't scratch often. Also my old projects were too nostalgic and I don't even know how I made these anymore :(
