### takes some practice to master

The user produces a new basis $\{\mathbf{u}$, $\mathbf{v}\}$ for $\mathbf{R}^2$ by moving points on a plane, and can then move a point around $\mathbf{R}^2$ by altering the $\mathbf{u}$ and $\mathbf{v}$ coordinates of the point. It takes some practice with the application to figure out what each slider alters and how they relate to each other.

### Works nicely!

Works nicely once I figured out how to use it?
