Category 1: Also a video-camera, albeit a small one that I can easily carry (like with a strap or something) that also has the resolution and whatnot of a professional video camera as used in proper films.
Category 2: A cute little kitten. Or actually, just my own cat (well, my family's cat).
Category 3: A nerf gun that looks like an iPod Touch for camouflage (I'm in an Assassin's Guild game which starts next week, you see...).
