A stealth plane in a suitcase - that was our first thought when we saw the Swinglet CAM. It's not quite that advanced, however; you'd need a shrink ray to achieve that, and sadly they don't exist. Yet.
This flying machine is still mightily impressive though, featuring a high-resolution 12MP camera for covert surveillance, or (if you're not a spy) aerial photography. A wingspan of 80cm and weight of less than half a kilogram means it can be launched by hand if needs be, while built-in artificial intelligence would enable it to even fly missions without any human input.
