It's not raspberry related at all, but since it's pretty cool, I thought I'd share this anyways with you tinkering folks.
Ever wanted to have a remote display for your computer? Even a remote network display?
Investing a little money and time, you can build yourself Niston Cloud's ReTINA. Totally without any soldering skills, right from COTS parts. ReTINA stands for Real Time IP Network Audio/Video and lets you attach a TV, LCD display or HiFi stereo remotely by network. Yes it works over WLAN, too. It needs no special application software, just use Media Center, VLC, iTunes or whatever you fancy. It works with PC and Mac.
