Nychos is an Australian artist who paints huge anatomical murals, covering the outside of buildings in the inside of creatures! Ewww!
It's super gross, but it's really well done - it's weird to see loads of nasty shark guts and think "That would look nice on the side of our office"!
Even things that don't have guts, like toys, have guts when he's drawing them! Gross!
Is this what T-rexes really looked like inside? Who knows! Either way, cool! But disgusting! But cool!
