I can play a 3D tour through the "run", which starts totally normally... but then we hit the moment where I leap out of England, straight over the channel and most of France, crashing through mountains and all (things get chaotic!) until suddenly I decide to run normally again

If you need a moment to refocus on something healthy: may I suggest this more-likely alt-history of velociraptor + human coexistence?

I cannot express enough how much I appreciate people who make distant & abstract science real like this.

A classic — most people don't realize this song was around long before Kermit made it famous
