Time crystals, AFAIK, are actually descriptive: they're crystals in the sense that they produce regularities through occupying the lowest energy state - they just do that in time, not just space.
So is Holographic principle in physics. Describing 3 representing 3 dimensional object in 2 dimensional surface is what holography is.
