Hi Angus
Usually it helps to start by getting something simple to work and then
little-by-little adding more.
E.g. Here's a working example with squares instead of bears, and limited to
just varying rotation ...
#lang racket
(require 2htdp/image)
(define blue-square (square 25 'solid 'blue))
(apply beside
(for/list ([i 18])
(rotate (* 20 i) blue-square)))
