great initiative :)

you'll need to have a look at the forward code and how we handle the
I think that just using the forward solution at first is the easiest.

the example you point out uses nilearn to make nice 3d slices.
you can also save a nifti file and use your favorite interactive
viewer (freeview, fslview etc.)

yes that's the way
let us know if you have more questions.
