The question that didn't get answered for me was "will it work with encrypted HDMI?" one hopes it does use one of the leaked keys and sniffs the stream .... if it does I want one .... otherwise it's not useful for me

I don't believe this works standalone with a TV. It needs an app running on your computer from the looks of it. I'm still waiting for an HDMI pass-through version myself.

It's great to see the Philips Ambilight concept democratized (I hope Philips doesn't have any applicable patents here), but the fact that this requires the video source to be a Mac / Windows / Linux PC is going to cut the potential audience way, way down.

I actually made a Standalone version of my own. All it needs is a composite video signal, so you can use it with any type of video source.

that doesn't really help me - I have an HDMI-only home setup - multiple HDMI sources switched by the AV receiver drive a single TV, I'd have to somehow create a parallel composite switch from all the video sources - Bunnie Huang's NeTV can almost do this (and with a nod and a wink one could hack the fpga to do it) so the technology is available to an enterprising hacker - whether you can make a commercial product that does this without licensing HDMI (or licensing and still making it open source) and without getting sued is debatable

All the devices that connect to my TV are HDMI as well. Put a splitter/converter after your AV receiver and you're good.

Some Sony TV's have this ... I like the effect during films, but I don't know why I like it... intuitively it feel like it should reduce the apparent contrast of the picture, but it instead feels like I'm watching a larger screen or that there's more going on in my environment. I'm going to hypothesise something to do with how brains process our peripheral vision. Anyway, not sure how much fun it would be to to run i…

I like this effect, but not because of changes to the perceived contrast. Often people turn off the lights during movies and this always bothered me because I lose my point of reference. It actually tends to give me nausea to have the only light coming from the TV. Having some sort of light whether its this, a nightlight, or a soft light from a different room tends to prevent this nausea.

Finally, someone else! People always give me strange looks when I complain about this.

I've wanted to make my own version for a while, but using a RBP (which I use for my media consumption anyway) was previously a deterrent.

I think you should make a HDCP pass-thru box because the easy of installation and practicality makes it more desirable to consumers (myself included). I have previously written software that breaks HDCP encryption as well as does a slew of other work arounds that other companies -- despite saying they do not -- actually employ to make input switching faster.

If you need to talk to anyone about HDCP let me know; I can either help or get you in touch with some people who can.

Jeff Atwood wrote a piece on bias lighting[0] for computer displays. I've been a fan of the idea and have been using the Ikea Dioder[1] colored, also in plain white[2], LED strips mounted behind my monitors both at home and work. It really makes things easier on the eyes when you aren't in a completely pitch-black room, not to mention the color effects are rather soothing. The Ikea strips are easy enough to mount to the back of monitors with a bit of velcro tape.

I suspect this is an effect of our Foveal Vision:

We only see things in the centre of the eye crisply and the effective 'resolution' reduces the further away we get from this point. Thus, perhaps, the extra colour is perceived as more screen rather than coloured wall.
