Years ago, they were peddling the amBX line, which was a set of lights, desk vibrators, and fans (yes, as in like, desk fans that blow in your face) that would create an immersive environment for games. Of course, very few games picked it up (we worked on it a bit for Second Life, and I did some silly things with it, super mario bros, and alcohol: https://www.youtube.com/watch?v=7kiKE3lif8Q). amBX ended up being mostly a failure, despite having fuck off HUGE booths on the gdc expo floor for at least 3 years running (Who else remembers the huge black blob? Great as a "meet me near [large obvious thing]" place. :) ).
Philips ended up either spinning or selling off amBX. It's still around as a set of crappy LED lights that burn out quickly (?!) and have crap for contrast and color depth. There's open source drivers out there if you look (including my half-done-maybe-still-works libambx).
Hue seems to be working out a bit better from what I'm hearing thus far. Might pick one up myself soon.
