Today on In Case You Missed It: A French artist created a remote-controlled robot disguised as a homeless man. It's name is Dirk. Additionally, a team of neuroscientists from Oxford University scanned the brains of 400 volunteers to create the most detailed map of the human cortex we've ever seen.

We've also got a man with a GoPro and a plan. He filmed himself building a gigantic vortex cannon then filled the machine with propane and let it rip. The results were *puts on sunglasses* explosive. As always, please share any interesting tech or science videos you find by using the #ICYMI hashtag on Twitter for @mskerryd.
