Trust me, I'm completely okay with big "glasses" and random trivia. Mmm, I love me some...trivia. But, like, actually. Did you know that they just discovered a warm-blooded fish? I thought that was neat. 
Also I have a teacher that spends all period discussing video games and comics and stuff with the class. It's great. He plays games with some of the students out of class. 
Also also, the colored text idea sounds fine to me, just maybe we keep it to one color per character, so that it's also a way to keep track of who's talking, hm?

Man, I really should watch some more anime. But I made a promise: nothing else until I finish Naruto. That was last year. Naruto is so long. And most of the other animes I've watched aren't really the, uh, cute kind.
