HOA president enters the room..

I knew a guy that was extremely upset to find out that there isn't a lenticular garage door product so he could have it display an "animated" image as it opened/closed.

Do you mean something like an e-ink display like on the BMW iX flow https://www.youtube.com/watch?v=BpKO-VuHMFA

Now that really would be science fiction haha!

Ah yes, the dynamic structural assistance cloak. It is on the list.

Along with the aerodynamic lift and propulsion cloak.

The future is super.

You could probably make a bulletproof cloak out of kevlar right now.

Might be a little stiff though.

This would actually be great! I guess the core challenge to achieving this would be in designing a metamaterial that meets the structural demands (strength-to-weight ratio) of a car body while also performing the complex wave manipulation required for invisibility. I wonder how far we are from reconciling those two very different requirements. Perhaps with the use of AI for metamaterials design we could be closer than we think!

Screens have a very limited range of brightness. More importantly, they only project a picture in one direction, so, if you can move laterally, you'll notice that it's a flat picture.

If metamaterials can alleviate any of that to some degree, they could make a form of invisibility cloak covering large objects practical.

Thanks for sharing!
