DrRacket's REPL supports image literals. The racket language also includes functions for manipulating these. Take a look at this program: http://img13.imageshack.us/img13/6493/drracket.jpg

In the "Definitions" pane at the top, we define three variables, bruce-lee, energy-blast, and terrible-accident. In the "Interations" pane at the bottom (here's the REPL), we compose them together.
