#Object Oriented
fun main(args : Array<String>) {
class local (val x : Int)
val y = local(10)
println("${y.x}")
Another variation of color-cycling a spanning tree generated by Prim’s algorithm. Here the periodicity of the color scale by tree depth is varied over time, alternating between emphasis of micro and macro structure. This idea was suggested in a Hacker News comment.
