LCD. One of the newfangled insanely-bright ones.

Huh. I should try that. Due to egging on from someone on 4chan's /3/
board, I bit the bullet and finally downloaded the latest beta and am
rendering a version with an image that has a better range of colours.
Holy crap 3.7 is faster than 3.5. So much so that I decided to really
push the settings...
I dropped the brightness from 10 to 2, kept 1600 samples, dropped error
bound to 0.01, 0.005 minimum reuse, 20 nearest count (to keep the sharp
edge of the shadow from being all grainy), but lowered recursion limit to 2.
I wanted to show as much of the colour-bleed effect as possible, so had
to hunt around for a better image...I actually tried setting gray
threshold to less than 0 (shouldn't that in theory increase saturation?
haha) but it only allows 0--1. :(
It's coming along quite nicely. The walls are a bit sluggish, but it
flies through the media itself like it's not even there.
I long for the day when I can use Moray in conjunction with this.
