Retro.
When the page loads, a user can see a purple/pink sunset surrounded by mountains and trees. There is a road with neon lines in the background with a logo saying Retro in the foreground. These elements were created using CSS gradients, shapes and shadows. When you click "toggle party mode", the Retro logo disappears. A driver with a helmet pops out saying "its time to drive". He disappears and the road then begins to animate. A city of dancing sound bars overlaps the sun as retro music plays. A car, also designed using CSS, begins to move in and out of view. This scene continues to loop, hopefully smoothly for most users.
Time to drive!
