You just need to save their life and run away before they have the chance to thank you. Seems to work for a lot of superheros, Maybe spiderman has a lot of social anxiety and thats why nobody can ever get a pic with him.

What is the use case for something like this? All that comes to mind is if you want to connect the display in a different room than the machine. But then you could just use one of those wireless HDMI dongles.
