Oh I see... this is awesome! :)
I did a quick test:
(require racket/gui
framework)
(define (sexp-editor)
(define frame
(new frame% [label "sexp editor"]))
(define canvas
(new editor-canvas%
[parent frame]
[min-height 480]))
(define racket-text
(new racket:text%))
(send canvas set-editor racket-text)
(send frame show #t))
It works great! I am shocked at how easy that was!

Oh, this is very nice! I didn't even know there was a way to embed a
REPL like this in slideshow! :)
