Financial talk

I was thinking about the Global Financial Crisis since it's a pretty hot issue nowadays. Does anyone know sites where I can see graphs and videos that might help when presenting? Also, as my original question says, is there something else that is interesting. I would also really appreciate it if you give me ways to present it such as videos, plots, debates(i'm doing the presentation alone though), etc...Btw, the presentation is 15 min long. thanks :)
