Is there a Scratch-like Arduino IDE?
It's in the works. A friend of mine, Ed Baafi, is working on a Scratch-like
interface for Arduino. I believe he may be presenting something in Cambridge (MA) at the
science festival this April.

Using a python shell script we (by we I mean Ed) were able to interface
one of my USB+XBee interfaces with the my ZB1 (arduino compatible board + XBee).
Text typed into an entry box was displayed on an LCD.
