Perspective's ending is crazy

After completing Perspective, a first-person puzzle game made by students at DigiPen, I noticed something strange with my desktop. Instinctively, I snatched up my iPhone and began filming. What ensued can be seen in the following video.

Also, make sure to check out the game itself. It's completely free from the site linked above and plays with perspective (ha) in some interesting ways.

(Sorry in advance for the swearing and world-stumbling. This was my first video for the public and I admittedly didn't think about what I was saying as I filmed.)
