About the alice in wonderland thing, i assume you mean the first pick, yes this was another pc in front of me who went to the mod from scratch competition (i went to the mod paint comp), let´ see if i can find a pick… here you go:
Personally I´m more of a fan of Mcgee´s version of the Alice story
About the lighted speakers, you mean the Philips AMBX Ambi light system right?
Well… I got them on a special deal on play.com about a year back, it was 50 quid for the whole setup (you can actually buy just the lighted speakers without sub, fan thingies and wriste rumbler pad, which obviously works out cheaper).
Personally, I quite like them, back then it was a pain as drivers where awfull, but it´s gotten much better now with updates since, you should know it doesn´t work with all games, I´d say 50-50 in my case, it does however work perfectly with music and videos. There´s also a software hack to make them reactive to sound instead of video, which rocks for music : )
Instead of picks, how a bout a video I took when i first got them? It´s done with a mobile phone so excuse the quality.
So in my oppinion, yes, they are worthied, plus if you get the whole fan thingie it makes games (as long as fully compatible as in, some will only work with light, no fan thingie) rather immersive, specially with the whole 3 screen stuff, for example, I personally didn´t think modern warfare was anything special, but this made it rather awesome (grenade explosions gave a sudden burst of air in your face, it´s hard to describe, but it does make it rather immersive).
EDIT: I should add the speaker sound quality does leave much to be desired, luckily you don´t need to use them (you can use the light and other stuff without connecting the audio) if you rather use your own speakers, as you can see in my pick.
