Below are some of the visual programming projects I've done in recent years. Some are meant to be viewed, some are meant to be played.
For best results, I strongly recommend using Chrome as your browser and a PC (many will not work on mobile devices).
A simulation to explore PID control and tuning concepts.
This is the visual from the home page. This one required some math review.
An interactive music visualizer. Perhaps the largest program I have written.
Good luck! (This will not work on touch devices)
A game of launching planets into orbit.
A simple but tricky game of color combinations.
A classic slider puzzle with animated graphics.
A simple visual of rotating squares.
