- Experiment 01: A "Radar" which tracks the position of the mouse, drawn using
  SDL2 primitives and a loaded image.
- Experiment 02: A stripped down version of the first experiment, using keyboard
  input to move the cursor.
- Experiment 03: An improved version of 02, which uses movement acceleration to
  make it feel better to use.
- Experiment 04: An example of simple gravity and bouncing simulation.
- Experiment 05: A "Spacewar" style gravity simulation, with a ship orbiting a star.
- Experiment 06: A modified version of 05, using delta-time scaling so it is
  framerate independent.
- Experiment 07: A clean-up of 06 so it's clearer to read and to further adapt
  into the Spacewar clone I'm planning on building.
- Experiment 08: A modified version of the simulation where the mouse is the
  "star." Fun to play aronud with.
- Experiment 09: A version of the simulation where the ship can be steered and
  accelerated. 
- Experiment 10: A version of the simulation where the ship has been given a
  sprite. 
- Experiment 11: A version of the simulation where the sprite animates while
  accelerating. 
- Experiment 12: A version of the simulation where the screen scrolls around
  with the movement of the ship.
