the Jungulator was made in Max afaik, did a gig or two at the same nights as Matt but heard nothing in the past few years. He had some technical issues with Max's performance and various other limitations iirc. Still, what he'd done with it was a good achievement.
IMHO it's a nice way to get people interested in making software, although the real deal is far more involved than GUI based "connect the code", so that'd be the big plunge.
