Good question! The entire scene you are seeing is being procedurally generated in realtime over 60 times per second (nothing is cached or pregenerated).  It does not necessarily compete with polygons in terms of visuals, but it is great for interactivity and procedural generation and so forth.  Everything you see is solid (vs being &quot;paper thin&quot; as most polygon games are).  The entire application is only a few megabytes large, so this make its easy for users to share their creations with each other (which could be just a few kilobytes in size). It is able to represent an area of several square kilometers with virtually no memory footprint (something of this detail would require several gigabytes of memory to store all the vertices for polygon data, not to mention the texture data).  This entire scene can change instantly based on user parameters. I don&#x27;t do a great job of demoing all of this but I should in the future. :)
