Portfolio Deal

I'm trying to figure out this whole portfolio deal, or whatever it's called.  I'm not exactly sure how to appropriately demonstrate what i've learned in this class.  I've had a few decent ideas, but nothing that seems both decent and is also not rediculously hard to do (I am pretty lazy and the end of the semester is sort of piling on).  

I was thinking of maybe use the flamethrower I built to set some stuff on fire in class, or maybe make something explode.  Although these are somewhat unsafe in a classroom setting.  

I contemplated making a flash animation, last semester I got reasonably good at flash.  That would be a a good way to show off multiple things I learned.  I don't really have a ton of time, and flash animation quality is directly proportional to the amount of time put into it.  Even a basic animation takes a fair amount of time.  

I think I might just make a webpage, or a video collage, or something that utilizes someone elses work rather than doing it all myself.
