Skreens

Looks like its first crowdfunding effort bombed, but Skreens is back and more affordable. For the unfamiliar, Skreens lets you show videos from multiple HDMI sources in one TV or monitor, and customize their layout using a mobile app. It also has a built-in web browser.

Crowdfunded projects pose a degree of risk for buyers, so be sure to do your research and fully read the seller's detailed description and production plans before plunking down your hard-earned money.
