        w ~
    N ( ! @ O ^ | .
    . . . . . . . .
        . .
        . .

- `N` initializes the stack with 10
- `(!` decrement and test for truthy
 - `@` on zero halt
- `O^O` output current number redirect to top face and output again
- `vw` redirect back to the `(` decrement to begin the loop again
