One Line: Inverse
(For some reason the program isn’t rendering properly on the blog, so here’s a .gif.)
When interacting with this program, in what way do you move your mouse? Are its movement patterns curved, straight, or twisty? The coordinates of this sketch’s line are influenced by the mouse’s, creating a basic interaction.
If I were to build on this program, I’d add an element that creates a graphical representation of mouse’s path, making it easier to observe mouse movement patterns.
