A Canned GUI-type Interface for Picaxe?


The picaxe is a great hobby platform, but what is needed is a user interface for projects that go beyond OLED type screens.
This would be canned code that runs on PC or Mac or android.
This would seem to be pretty simple, communicating via serial port on USB.
Even a terminal program would be useful.
Anyone have any ideas on this? Has this already been done?
Note: not all locations have wifi or internet.
