22Moo has updated their VR glasses product line with the VG-SD (also going by ZuneVG). Simulating a 35" 2M away, the VG-SD supports direct input from your video iPod or Zune, as well as SD A/V inputs from all of the latest gen videogame systems (well, really anything with an RCA output).
The 320x240 model runs $250. The glasses feature a USB-rechargeable lithium ion with an undisclosed runtime. I fully believe in the technology VR glasses, especially with the popularity of PMPs with tiny screens. If only they didn't make you look like a complete tool, blinding you to the peanut-throwing bullies on planes everywhere.
