A more expressive way to write code?

I would like to have some more pleasant and expressive user interface than the mouse and keyboard for programming.
Is that possible?
Pen and paper? (HHOS)
Edit: With pen and paper you can structure your code however you want. You can use any symbols you fancy. I like blank paper, with no grid/lines.
Can you outline the expression bottlenecks with the current approach? Where do you feel the mouse and keyboard fall short? What is 'missing?
Give the PS4 "dev-game" Dreams a spin, you can program by physically connecting logic gates and moving wires and gadgets. You wiggle the controller to move around the screen.
Much less efficient but immensely more (visually and mechanically) satisfying than typing. I personally love it.
Depending on what you mean, there's some work on voice coding (dictation plus tooling, basically), or perhaps you want notebooks or literate programming?
