 The effect is done via VisualEffect entity. The model is a plane and gets scaled to fullscreen (with z = -1).
-The input texture (figure 1.1) gets wrapped around via abs(atan(y,x)) (figure 1.2). You can imagine this as a cylinder with infinite length and you are looking into it. As the shape can be adjusted we can reach square, circle and squircle (figure 1.3).

 The shader applies then some glowing lines and adds a opening door. Artists don't have to care much about it - the shaders does it on it's own. The interesting bit though is the coloring of the door. It's taken from the input image and walks counter-clockwise (figure 1.4). The shader rotates it and zooms in, so we get a gradient (figure 1.5). Finally it gets mixed with the glowing lines to some extend to get a smoother transition between tunnel and door and a standard tint gets applied (rgb: 0.5626,0.3587,0.0858).

-All in all it does some computation (atan, length, distance and sin/cos and 2 texture lookups), but still runs smooth even on my old GeForce Go 7950. The compiler in 6.14.11.7948 spits out 128 instructions, 5 R-reg and 1 H-reg, so it's not really cheap - later cards drivers may cut this down a lot, based on the optimizations they are able to do.
