🧪 Interactive 2D Ulam Spiral Simulation

This interactive simulation allows you to explore the mathematical principles behind the Ulam spiral's creation. By adjusting parameters like numbers and their sum, observe how the spiral pattern emerges – a beautiful demonstration of number theory. Added a slider that controls how many numbers of the spiral are actually plotted, wired directly into the drawing loop.
