I crave mental lint. What are some interesting facts that the hivemind (you) have stored away? (slrpnk.net)

Look at one thing, then quickly at another (only moving your eyes). You quite literally were blind for a moment there due to saccadic masking: https://en.m.wikipedia.org/wiki/Saccadic_masking

Okay. Ever wonder why pigeons bob their heads? It's so that they can perceive depth. Animals with front facing eyes like ours can tell how near/far something is based on the angle formed by our eyes (called stereopsis). Pigeons, being side-eyed, don't have that option, so instead they compare the percieved size of things as they bob. Things that are closer will "grow" more than things that are far away.
