You should be able to see the blob form models – perhaps there's some error when it runs on your system. It relies on floating-point textures which aren't supported everywhere
Yes with s=1?d=-4 the models are completely clear. I assume the semitransparent glittery look is intentional artistic choice."weird blob" weren't my words but I can imagine how someone could describe it that way considering that half of the time you see the transition animation during which it's much harder to recognize the object.
