Ok, so, I'm in my room, no real lights on besides the light coming from my laptop, and I'm just sitting around watching Youtube videos and occasionally checking Spam. 

And my laptop has a charger (whom you may remember as the accessory of my fez-wearing bedside lamp) which has a small light on the end of it that attaches to the computer. When plugged in, this light comes on orange, and then it turns green when the system is finished charging. 

And so while I'm derping around on Youtube, I'm idly holding my thumb over that charger light and I notice that, in the dark, the orange light essentially shines through my thumb and kind of makes it look like my thumb is glowing. 

Mildly amused by this, I sort of kept my thumb there on-and-off for a while before I realized that the light had turned green, as it does when I'm finished charging.

But what made me notice this (at least initially) was not the presence of green light but of [i]no light at all[/i] as, once the light changed color, none of it shined through my flesh at all. My thumb was enough to totally block the light. 

Which is kind of crazy, since the light didn't appear to change in intensity at all - only color. 

Man, light is weird.
