Interesting indeed! Tell me if I've understood you correctly. You'd
display this code:

def func(x):
    for n in range(1, x):
        while n < x:
            if n % 2:
                n = (n + 1) * 3 / 2
            else:
                n = n * 2 + 3

with stripes of colour, with the entire first column of spaces all
tied to the "def", and then the next block of four tied to the "for",
etc? That'd be pretty cool, and a neat way to help people transfer
their skills from Scratch to Python.

(Would "else" be in the same colour as "if"? What about "elif"?)
