Vector Algebra Demos

What started as a simple tool to illustrate the graphical addition of vectors has ballooned into a suite of demonstrations and tutorials for a variety of vector algebra concepts and operations.  All operations are demonstrated both graphically and analytically so that one can practice the calculations and verify the results.  Included in this suite are a combination of 2D and 3D demos:

• 2D Vector Components
• 3D Vector Components
• Vector Addition
• The Dot Product
• Vector Normalization
• Vector Projections
• The Cross Product
• Finding Surface Normals
• Closest Point on a Line
• Closest Point on a Plane

This is a work in progress and will continue to evolve as I receive feedback.  Please let me know what you find useful, what needs to be improved, or if there are any demos that should be added.
