I reposted this here once before with more description. It’s originally from 2008. Now, miraculously, someone is doing it, which is what prompts this re-re-post. I wanted to share the link to the inventor’s project. Check it out on Kickstarter!. Kind of reminds me of my folding iPhone, though mine didn’t fold. I still don’t see the need. Two screens, closely fitted, would be fine. And could’ve been done ages ago.
