[racket-dev] [racket] response/xexpr missing?

Thanks.

#lang racket  ; A picture
(require 2htdp/image)
(let sierpinski ([n 8])
  (if (zero? n)
      (triangle 2 'solid 'red)
      (let ([t (sierpinski (- n 1))])
        (freeze (above t (beside t t))))))


This is a revision. I don't  nkow if it fits, tho. The call to freeze
can be anywhere around the result if that helps at all.
