Gyration has unveiled a pretty interesting presentation device that enables you to incorporate a more dynamic approach to your office and boardroom presentations. Standard presentation ethics conclude that you should just stand by your notebook, interrupting your speech on occasion by advancing to the next slide after pressing a button on your notebook. The Gyrotransport Air Mouse does things differently, as this device comes with 1GB of built-in flash memory to store all your presentation files. It also comes pre-loaded with the GyroTools Media Control Software Presentation Edition for Windows which gives the user instant access to more than 80 multimedia and presentation tools. Once you plug in the receiver into the USB port of any Windows-based computer, you can start controlling the slides via your hand's motion. Imagine turning up the volume by sweeping your hand upwards, while lowering the hand will result in a lower volume. You can pick up the Gyrotransport Air Mouse for $199.

Pros : Uses motion sensor to control flow of presentation
Cons : Hand could get tired
