The brick was about $5, so it wasn't too bad. As for PowerPoint... I made a few, but I only used them as guidelines as I spiced everything up with my own commentary. Though, my funniest one used sound effects and Ren's laugh, and the subject matter was about Zero from Megaman X. Having sound effects thrown in for humorous bits helps, but otherwise, just use it as an outline and not as the actual presentation. It's like doing a presentation with charts and graphs.
