Is it possible to make a object repeat itself inside itself via shader?

Hi,
I’m new to shaders and I’m trying to code a shader where the object repeat itself inside itself.

I’ve made a mockup of the desired effect.

Is it possible?

Thank you!

If I get what you mean, all you would have to do is duplicate the main shader pass multiple times, each with a size decrease in the vertex shader.

Pass {
    CGPROGRAM
    ...
    v2f vert (appdata v) {
        v2f o;
        v.vertex *= 0.25;
        o.pos = mul (UNITY_MATRIX_MVP, v.vertex);
        return o;
    }
    ...
    ENDCG
}

Pass {
    CGPROGRAM
    ...
    v2f vert (appdata v) {
        v2f o;
        v.vertex *= 0.5;
        o.pos = mul (UNITY_MATRIX_MVP, v.vertex);
        return o;
    }
    ...
    ENDCG
}

Pass {
    CGPROGRAM
    ...
    v2f vert (appdata v) {
        v2f o;
        v.vertex *= 0.75;
        o.pos = mul (UNITY_MATRIX_MVP, v.vertex);
        return o;
    }
    ...
    ENDCG
}

Pass {
    CGPROGRAM
    ...
    v2f vert (appdata v) {
        v2f o;
        o.pos = mul (UNITY_MATRIX_MVP, v.vertex);
        return o;
    }
    ...
    ENDCG
}

Something like that.
