The new Interact.jl package allows you to use interactive widgets such as
sliders, dropdowns and checkboxes to play with your Julia code within an
IJulia session. It is pretty neat, in particular the `@manipulate` macro.
For those times where IJulia is not convenient, but the console is, I've
made a small wrapper package GtkInteract.jl that creates these widgets in
Gtk with the expectation that Winston will be used for graphics. If you are
interested in such a thing, you can try it out by cloning the package:
Pkg.clone("https://github.com/jverzani/GtkInteract.jl.git";).
