We’ve all seen the bouncing screensaver. And we’ve all watched, hoping it would fall into the corner. Oh, you haven’t? Well, watch this documentary footage of the adventure you’ve been missing.
The screensaver isn’t mysterious. It moves in predictable ways, meaning we can calculate how often it’ll hit the corner (and if it will hit a corner). So let’s start with some assumptions.
- The bouncing object is smaller than the screen.
- It starts in the upper left hand corner.
- It moves at a 45 degree angle.
- It bounces perfectly (i.e. it always is moving at a 45 degree angle).
