Ugh. Apparently I can get... well... not motion-sickness, because I'm not queasy... but my vision has been seriously upset by a computer game for the first time ever. I've been playing From Dust, and I'm on a map that tilts/rolls backwards and forwards, and after switching back to my PC I've still been seeing things rolling backwards and forwards on my monitor. It's like the weird vertigo you get after you've stepped off a ship and it takes your brane a while to adjust to the fact that the horizon is stationary, and you still see it moving as with the waves.
Bleh.
Bleh.
