 it lands the ring snaps open past its own radius and pulls back onto it: a violet column tears up
 out of the middle, tendrils crawl outward to the boundary, arcs run around the rim and the whole
 disc burns. It holds there re-striking and hauling the air up into the pillar, then collapses to a
 thread. The circle you measured out before the click is exactly the circle you get.

 Everything you can see is generated. There are no textures, no sprite sheets and no meshes on
 disk except the character: the crystals are procedural geometry, the bolt is a strip of ribbon
 placed entirely by a vertex shader, the meteor is an icosphere cratered and sliced by fracture
