Free DIY blue light box!

So I had this awesome idea:

A usual trick for shifting to an earlier sleep cycle (or for treating seasonal affective disorder) is to spend some time looking at a light box shortly after waking up. If you have a light box. And if you have time. And if it doesn't bore you silly.

But a little bit (400 lux) of blue light is as effective as a lot (10,000 lux) of white light. And I spend hours staring at a light source -- my monitor -- most days. My monitor's brightness, 290 cd/m2, converts to 912 lux, which I assume means that it can give me 304 lux of blue. So how about this: Read all of my morning daily stuff (Livejournal, comics, news, FML, etc.) on a bright blue background! (And this is the perfect excuse to do things my mother told me not to: Sit too close to the screen, and have the lights off in the process! (Diluting the blue light with white reduces its effectiveness.))

It doesn't take any time out of my day at all, and requires no new equipment!
