Very useful idea for a project get pre-reading children started. It can be implemented analogously using mouse & message passing, by having children click on icon sprites to control the turtle, which gives more opportunities to give feedback to the child. I've begun implementing such a project.
I did a one key project in logo (before I found scratch) where my children would sound out the keys strokes RRRR to do a square and so on and then press a button to repeat the pattern (see www.redware.com/logo). It works well with 3-5 year olds but unfortunately scratch does not have memory so could not implement here.
