NEC has some pretty crazy ideas when it comes to smartphone design — as we discovered when we checked out the dual-screen Medias W at Mobile World Congress back in February. And its latest offering is just as outlandish.

Meet the Medias X 06E — the world’s first smartphone with a water-cooled CPU.

Aside from slightly different form factors, today’s smartphones all look pretty similar; they have large displays that take up the majority of the space, and just a few physical buttons. But NEC is hoping to throw something different into the mix. The Japanese company has today unveiled the Medias W N-05E, a folding smartphone that has two 4.3-inch displays.
