It would be awesome don't you think ?!!
Since Pd already is, imagine a little one you can carry on your pocket. I have lots of sound-music applications on it (elektroplankton, korg ds-10, nitrotracker, lots of home brew).. they are great, but we all know they can't do what pd can. Imagine a little vanilla, you just mess with the objects on the touchscreen, man .. who is interested?
