The Double from DoubleRobotics: your face on an iPad on a stick on a bobbin.
Out there. Rolling about the place.
The maker sez:
Double is the simplest, most elegant way to be somewhere else in the world without flying there. The minimalist design and intuitive touchscreen controls allow you to freely move around without inconveniencing others. You can stay at eye level, whether sitting or standing, by adjusting your height remotely, which makes conversations fluid and real. Retractable kickstands will automatically deploy to conserve power when you are not moving around. Efficient motors and lightweight design give Double the ability to last all day without recharging the battery.
