Eh, I stay mainly in 2D anyway; never needed depth perception before. The exception was yesterday when I hit an 18 inch high tree branch that I judged to be a small bundle 1 inch high off the ground until I was right up on it; had to pick it out of my rear wheel, the noise was getting to me.

I swapped into 3D after that, which is cool but takes a lot of focus and disables the synesthaesia, which is ... distressing, and confusing. As an interesting side effect, I took a corner fast up in the woods and saw two large things flying through the air that I couldn't identify. Switched back and ... oh, deer!

The weird thing is everything looks like fake, plastic movie/video game rendering like that to me. I was always perplexed by people with the 3D glasses like "Oh wow it looks so REAL!" when I'd look at the thing and go "WHOA that's fake!" My brain seems to use 2 eyes by making one dominant, and then cutting off the edge of the other and stitching the image together so I get a panoramic 2D view instead of a 3D view. Guess I'm just in that 5%.
