Design of the Week: RD Time Extrusion

This week's selection is the RD Time Extrusion. What is it? We're not sure, but the designers, Nervous System believe it could serve as a pencil holder, as depicted here. You're free to figure out other uses for this unusual item. 
 
The item was designed mathematically, like many Nervous System products, and is freely available for download on Thingiverse. They say: 
 
Created through a 2D simulation of reaction diffusion extruded through time. The top of the model is t=0.
 
Of course, we knew that already.
