Processing Basics

I've been working on a few Scala/Processing projects to get the hang of it, and today I started translating some of the basic examples to Scala just to make sure I was getting it.  This one is the Basics/Array2D example:

size(200, 200)
background(0)
val maxDistance: Float = dist(width/2, height/2, width, height)
val distances = Vector.tabulate(width, height){ case (i, j) =>
  dist(width/2, height/2, j, i)/maxDistance * 255
}

for (i <- 0 until(height, 2) ; j <- 0 until(width, 2)) {
  stroke(distances(j)(i))
  point(j, i)
}

To me, that's a lot better than the original Java.  Less clutter, more higher-level constructs.  Even in this simple example, the Scala code does a better job of showing the intentions rather than the specifics of the algorithm.
