Idea for mtx footprint

the ground is a purplish pink ring of void goo like "lava lamp-type goo". it's dripping up like a lava lamp into bubbles of fuzzy void.

bubbles rising up from the ground to then pop at various heights. the popping could be implosions that collapse into mini black holes.

movement or steps would produce one small bubble to rise up out of each footprint to then pop in that manner.
