While the upcoming 3D gadgets such as Nintendo’s 3DS portable gaming system are definitely interesting, you might be feeling nostalgic and long for those old-fashioned 3D systems that slapped an electronic display right over your eyes. Well, if you’re willing to shell out $750 (or maybe more), you might want to head over to eBay and check out a VFX3D virtual reality headset that is up for auction. This helmet straps onto your head and offers dual-stereoscopic 3D images along with simple head-tracking technology that worked with some old 3D PC games like Descent 3 and Unreal Tournament. The LCD displays only offer a 263 x 480 pixel resolution and only 263 x 240 in 3D mode, so don’t expect too much. The original system sold for $1800 and if you decide to pick it up, the drivers and SDK are still available online.
