I was using Stumbleupon and came upon this: http://www.stereopsis.com/flux/
It's
a Windows app that adjusts your monitors color and gamma to the time of
day. I thought "Hey, neat. I'll be trying that." I installed it and
it did as promised. I loaded up some Minecraft and too my great
surprise, I was able to see everything at night. It was dim, but not
pitch-black. I could even dig with no light and still see well enough.
Keep in mind, I've only ever played Minecraft on my computer so if it's
not supposed to be pitch-black at night I don't know that. It might be
that my monitor was in serious need of adjustment as I am using a 36
inch flat screen tv as a monitor.
