@Sheehan There is now Interact.jl (Pkg.add("Interact")) which lets you travel your for-loops with sliders and such widgets, to put it one way. Here's an example notebook showing how you can do interactive plotting with Gadfly or PyPlot: http://nbviewer.ipython.org/github/JuliaLang/Interact.jl/blob/master/doc/notebooks/Interactive%20Plotting.ipynb
