Whether you're planning on a repeat viewing of Dark of the Moon or you're headed in to see the robotic mayhem for the first time, stay true to your inner child by wearing a Transformers 3D Helmet ($10) into the theater. Available in Optimus Prime or Bumblebee models, they contain the same RealD lenses you'll receive at the theater, letting you look either less dorky or more dorky (depending on your level of robo-love) while you enjoy the 3D action.
There isn't really a good way to describe this Animatronic Triceratops ($350,000). (Looking to construct your own Disneyland boat ride? Have a Michael Jackson-like obsession with childlike things? Don't have the money to pay for CGI on your indie Jurassic Park remake?) So, instead, we'll tell you that it's 20 feet long, weighs over 1,300 pounds, tracks your movements with its camera-eyes, has tons of digital tech and a 1,000 watt speaker inside to let it move and sound like the real thing, and totally won't grow cognizant of its surroundings and tear through your home like a bull in a china shop.
When we first saw the latest iPod shuffle, our immediate thought was "make it any smaller and you'll have to build it into the headphones somehow." We doubt anyone was listening, but that's pretty much exactly what has happened with the Sony Walkman W260 ($60-$80). Designed with active users in mind, the W260 is rinsable, wearable, and water-resistant, and offers features like quick charging, a black or white casing, and either 2GB or 4GB of storage.
