Examples are the Moire patterns and the bouncing 3D cube thing.

I thought those were just more-detailed variants of Grampian/Hercynian/Caledonian and BorgBeat?

I do admit, the cube on the HSX is pretty cool. It's like BorgBeat on the empeg, but its faces have a symmetrical version of the Grampian/Hercynian/Caledonian thing running on them. It's nice to have more shades and a higher rez.
