Other times, they’re cute.
A lady named Pritika Nilaratna, a New York resident and creative technology designer, made this flying blimp, which roams around inside buildings and acts cute. That’s its job: being socially awkward and flapping its wings excitedly when you talk to it. Slightly less nefarious than spying on you, for sure.
Blimps are cool because they’re lighter-than-air. That means staying aloft takes almost no energy, and moving takes a lot less. So Ollie runs on just a tiny battery.
The coolest thing about the Ollie design is that it’s released under the Creative Commons license. It’s not completely open-source, but it’s almost the same: use the design as you please and make whatever you want, so long as you give credit to the original creator, and also release it under the same license. Long story short: the design is free to use. Go buy a few parts and build your own. It’s basically just a mylar balloon, a battery and a couple motors.

There’s only one thing it’s missing: a little speaker somewhere, so it can make some kind of sounds when it’s excited. Add those when you make it.
You can check out the website for Ollie, which is shown at the end of the video. Or you can just go to meandollie.com.
Here are a couple resources for making your own version of this thing:
(Consider getting a bigger balloon, and adding one of these.)
