Well, this is unsettling! It's a Japanese spherical drone spyball, flying around and peeping on anyone and anything it pleases. No, thank you!
Developed by the Japanese military, this reconnaissance drone is clearly meant for the battlefield, not the changing rooms at Macy's. It's a pretty impressive piece of tech, as you can see in the below video, with it able to keep in control really well as it flies around.
But still, keep that thing away from me. I don't care how impressive it is or what it was built to do, it still has the ability to spy me while I shower, which is all I need to know.
