There's a term for this, "exploratory interface". Where the user is free to
learn what something does by simply pushing buttons and watching what happens.
Each control has obvious feeedback so they can learn by doing and each
operation is undoable so they can't truely screw anything up. Most
version control systems have the latter nature inherently.
