Siliceous ooze

Microscopic marine organisms such as diatoms and radiolaria use silica to produce skeletons of remarkably complex design.  

At the end of their life-cycle their skeletons deposit on the ocean floor forming a siliceous ooze.

Falling in love with the elegance of these intricate structures, I couldn’t resist the temptation of feeding neural networks with some of these beauties and stare at them morphing between each other.
