Move the joints of your stickman by clicking and holding on them, then dragging your mouse. All body parts are rotatable. Move the entire stickman left and right, up and down, with the arrow keys.
This project actually uses trigonometry! It just so happens to be my first project to but it to good use. (The Trig calculator also used trigonometry, of course, but there was no practicality in that.) Enjoy!
Coming up next: a stickman ANIMATOR!
