I kinda lost motivation to work on Mantra. I'm somewhat pressed for time (thanks college), and really just distracted by any given thing that comes into play around here. I'm on spring break now, and all I get to do is a little bit of programming and a lot of research for an upcoming paper (the topic is fun, but that's the only reason I might get it started, I'm kinda putting it off right now..).
This is why I opted to keep the source online -- if anyone wanted to pop in on the project, take it over, work on it, whatever, it's there (all you have to do is let me know). I'm sure I'll revisit it in the future, but by then, I probably won't remember what I wanted to accomplish with the project.
Sorry for those who were looking forward to it. I guess I don't work well when I'm by myself, because the only thing keeping me working on it is me, and that usually just isn't enough.
