Interface and gui 3d

So in the 8th annual bloxy awards voting place, it had a voting system where when you clicked the game you voted for it hovered it follow your mouse and had a 3d look, does anyone know how to pull this off? Take a look at the game yourself 8th Annual Bloxy Awards - Roblox Try voting, since i cant show as I voted already.

I’m pretty sure it used viewport frames to establish it’s effects.

Just took a look at it and what they did was a trick known as rasterization (viewport frames but from the ground up). Basically they have an imaginary point in space which will call the camera and they use rotation with vectors. They then project the pixels to rays from the pixels from the cameras near fov. If you want it to rotate however idk if u can make the background of viewport frames transparent
