[RMVX] SCRIPT HELP?

Hi everyone, I am fairly new at this, so if this is the wrong place to post this let me know :D

Anyway, I was wondering if anyone knew of/could possibly create a script for RMVX which makes the message box appear similar to that of closed captioning on televisions. I'm working on a "mini-project" of sorts and it would really help.

Thanks for all your help - Vanilla
