Might be even better if like a chameleon it had some lcd panels that could give off the average color of whatever it's trying to blend with. In the video, it looks extremely invisible against a gray background, because the drone is grayish. But it's not that great against a green background. If it could change to green, or to white, or to black, depending on the background, it would be excellent.
Also, we already a form of invisibility. It's called cover of darkness, and operating at night. Most stealth ops prefer the night for that reason. But it's not always feasible, because while you're more invisible at night, so too are all your enemies. Daytime lets you see your enemies, which is good, and this motion blur effect provides a good asymmetry where you can stay invisible while the enemy is not. They'll just have an ambient some of hundreds of whirling motors, but can't pinpoint any in the cacophony.
