If you enjoy Mandelbox, then be sure to try this out!
It's like Mandelbox done right.

CPU ------------------------------------

control.maxSteps = 20
control.cx = -0.29001915
control.cy = 0.099999756
control.cz = 1.0099993
control.cw = 1.3200002
control.dx = 0.35000002
control.dy = 1.3
control.dz = -1.1000001

GPU ------------------------------------

float DE(float3 p, device Control &control, thread float4 &orbitTrap) {
    p.xz = mod(p.xz + 1.0, 2.0) - 1.0;

    float4 q = float4(p, 1);
    float3 offset1 = float3(control.cx, control.cy, control.cz);
    float4 offset2 = float4(control.cw, control.dx, control.dy, control.dz);
    float3 ot;
   
    for(int n = 0; n < control.maxSteps; ++n) {
        q.xyz = abs(q.xyz) - offset1;
        q = 2.0*q/clamp(dot(q.xyz, q.xyz), 0.4, 1.0) - offset2;
       
        ot = q.xyz;
        orbitTrap = min(orbitTrap, float4(abs(ot), dot(ot,ot)));
    }
   
    return length(q.xyz)/q.w;
