| In the sketches I call floating midpoints, two points are animated a various relative speeds, and the midpoint of the segment connecting them is traced. | |
| Floating midpoints #1 (Java Sketchpad - based) | Floating midpoints #2 (Java Sketchpad - based) Tracing midpoint between 2 points moving on concentric circles. |
| Floating midpoints #3 (Java Sketchpad - based) | Floating midpoints #4 (Java Sketchpad - based) Tracing midpoint between 2 points moving opposite directions around concentric circles. |
| Floating midpoints #5 (Java Sketchpad - based) | Floating midpoints #6 (Java Sketchpad - based) Tracing midpoint between two points moving on a circle. |
| Floating midpoints #7 (Java Sketchpad - based) | Floating midpoints #8 (Java Sketchpad - based) Similar to #2 with different speeds. |
| Floating midpoints #9 (Java Sketchpad - based) | Floating midpoints #10 (Java Sketchpad - based) Tracing midpoint between 2 points on externally tangent circles. |
| Floating midpoints #11 (requires GSP Viewer) | Floating midpoints #12 (Java Sketchpad - based) Tracing midpoint between two points animated on a circle. (Extension of #6) |
