Algodoo

Algodoo only simulates air resistance and buoyancy. So, I tried to make a script that can also simulate lift! This is a wing (box) that can experience "lift" when moving at an angle to the air. Try throwing it around!
It's not at all perfect fluid dynamics, but I'm pretty satisfied with it. All it does is calculate the components of the velocity of the wing, and apply a force whose strength is according to the angle between the wing and the air. The direction of this force is normal to the long side of the box, which is why the thruster that applies the force rotates with the body.
The wing only has a script that defines three variables, while the thruster does operations on those variables and applies the result as force to the wing.
