The Glyph, a mobile personal theater head-mounted display, hit its Kickstarter goal of $250,000 in just four hours. With 25 more days to go, it already managed to raise $704,999 from 1,486 backers.

　　Avegant, the company developing the Glyph for the past two years, says that it's meant solve the problem of poor image quality on small mobile devices with what it calls "Virtual Retinal Display," which projects images directly to your retina, creating sharper, starker images.

　　The Glyph, which was demoed at CES 2014, looks like a simple pair of headphones, but you can flip down the headband, turning it into an HMD. It uses a simple HDMI input to connect to any of your devices.

　　"The Glyph is also great for gaming, whether in playing Call of Duty: Ghosts on your PlayStation or Real Racing on your mobile phone," the Kickstarter page reads. "And with an integrated 9 Degree of Freedom head-tracker, a whole world of interactive gaming, Point of View (PoV) imaging and interactive storytelling is within our reach."

　　While it's not built specifically for games like the Oculus Rift, the Glyph contains a 3-axis gyro, accelerometer, and a digital magnetometer to allow head tracking in games.

　　You can learn more about the Glyph and become a backer for as low as $5 on its Kickstarter page. Pledging $500 or more will actually get you a prototype of the device.
