Drawing Lines With a Pen Can Magically Control Creepy Crawlies

By Casey Chan on at

I've always wondered what some bugs are actually aware of. Can they see what's happening above them? Do they realise when we're screwing with them? Or can they only make 2D decisions in a 3D world? Like this guy shepherding a bug on a piece of paper by just drawing lines with a pen. The bug sees obstacles pop out of no where and has to change course. It makes for a pretty effective way to control such little critters.
