This is a program I started making a while ago, although I never really got around to finishing it. I might later on, but I'm going to put it online for anybody to download it in case they want to finish it. It is in TIBASIC for the TI83+/TI84+ series. It definitely isn't completely optimized at the moment, partially because I wanted readability. It is meant to serve as an aid to those learning about vectors because it offers (or it was intended to offer) a few handy features:
 Visual plotting (including addition and other operators) of 3D vectors
 Conversion between equation formats
 A table of values for vectors
 The ability to calculate the angle between two vectors
 The ability to calculate where two vectors intersect
So far, all it can do is visually plot 3D vectors, which is kind of cool, and adjust the window. Here's a screenshot of it:
It can be downloaded here:

that's pretty cool. Can the camera by shifted over or is the original always kind of fixed there on the left?

It can be shifted over. :)

Nice work with the graphing ability. :thumbup:
Perhaps you add some of these features (should be easy, as I have already done this on my 89):
 vector length
 unit vector (and graph)
 dot product
 cross product
 triple product
 projection
 bound vectors
 check for orthogonal
 check for orthonormal

Well, I could, but I've kind of stopped working on this. I might continue working on this sometime, though. Good suggestions, though.

Yeah dot product would be a great addition
