In this interactive invitation trigonometry is used in the code to create exciting visuals and interactions. These visuals include a size changing sun or moon, and a school of swimming fish. The interactions take the user on a journey with the movement of their mouse. From a peaceful sea with a sun with a mouse at the top left to a stormy night sea on the bottom left. Moving your mouse to the right where the invitation details lie, we have a party feel, with greater waves with a sunset pink background on the top right and big waves with a hot pick background with the feel of an equalizer on the bottom right.
