The Lab

The Lab is a compilation of 8 different VR experiences created by the Valve Corporation. They pulled know stops in showing the capabilities of VR through all the experiences. A few examples of the included experiences include viewing the human body through a series of CT scans, visiting our solar system, and visiting exotic locations.

The best thing is it is free to play, so if you just spent a bunch of money on a new VR setup, this would give you plenty to do until you purchase other popular VR games.
