Draft: Given two positive numbers h and w, output the first w numbers in the following pattern: 1, 2, ..., h-1, h, h-1, ..., 2, 1, 2, ..., h-1, h, ...

(If there's a better way to describe that, please suggest it)

"bouncy ranges"?

Draft: Output all pandigital numbers

@cairdcoinheringaahing Well, that actually gives me a slightly different idea...

Draft: Given a nonnegative integer h, outputting its "bouncing" sequence: h, h-1, ..., 1, 0, 1, ..., h-2, h-1, h-2, ..., 1, 0, 1, ..., h-3, h-2, h-3, ....., 1, 0, 1, 2, 1, 0, 1, 0

0 -> 0
1 -> 1, 0
2 -> 2, 1, 0, 1, 0
3 -> 3, 2, 1, 0, 1, 2, 1, 0, 1, 0
4 -> 4, 3, 2, 1, 0, 1, 2, 3, 2, 1, 0, 1, 2, 1, 0, 1, 0

Draft: Given an integer n >= 2, output ascii-art of n stick figures holding hands. Here's n = 3:

\O  O  O/
 #--#--#
/ \/ \/ \

Heh. It occurs to me after the fact that this looks rather like the outer stick figures are stabbing the middle stick figure...

\O   \O/   O/
 #--- # ---#
/ \  / \  / \

Draft: Given a direction vector [x, y] ([0,1], [1,0], [-1,0], [0,-1]) and a mirror (<>/\^v), output the vector after it goes through the mirror (> is always [1,0], < is [-1,0], ^ is [0,-1], v is [0,1], / maps [0,-1] to [1,0] etc. and ` maps [1,0]` to [0,1] etc.)
