Heh, I thought the moire patterns were artifacts of my monitor, not the picture itself. I really can't tell, though.
I mean, the right side seems to keep the alternating red and green lines more distinct around the bottom half of the pic (the left side makes it look like the green lines alternate with dark ones, perhaps because the red and green lines are separating more), but I can't tell if that's a result of the filtering being applied or just the orientation of the lines (slanted left rather than right).
I'm guessing, if the moire is a part of the pic, that may be where the Mipmaps blend? And thus they're a clue as to what's being done to which side?
Testeron, eh? Spotting the difference sounds like a job for Superon. =D
