Show HN: Ruby Heap Viz – An interactive Ruby object graph visualization (github.com)

I've seen this in action a couple of times and it is awesome. This is a fantastic way to demo the heap to people who have had some experience in Ruby, but only a touch of compsci fundamentals.

To stress your browser, open viz.html and in irb do:

    module Example ; class Foo ; def bar ; end ; end ; end
    100.times {  Example::Foo.new ; sleep 1 }

    GC.start

Any known results with actor-based scenarios, such as with Celluloid?

Those situations tend to be infinitely recursive, but would be priceless to map visually.
