This arcade project simulates how SINE waves work.

**Two sine waves** — white and blue, both scrolling continuously with phase shift illusion.

**Circle visualizer** — rotating point on the left showing that sin is just the y component of rotation, with a line connecting it to where the wave starts.

**Interference** — where the two waves cross or get close, it flashes cyan showing constructive interference.

**Slider** — vertical yellow line at x=100 showing the current amplitude value of wave 1 at that point.

**Controls:**

- A = increase wave 1 frequency

- B = decrease wave 1 frequency

- Up = increase amplitude

- Down = decrease amplitude

- Left = decrease wave 2 frequency

- Right = increase wave 2 frequency

**Smooth transitions** — all changes lerp smoothly instead of jumping.

**Negative frequencies** — both waves can go negative making them scroll backwards.
