Another one I wished I had years ago. Please improve on the controls and I will have a tool, which will help my daughters, when they will struggle with that stuff at some point in their life.

I'm not smart enough to use it properly, but it looks like a really helpfull tool :D

I've been wanting something like this for so long since I found it hard to grasp linear algebra, until very recently. Wish the controls is a lot easier, maybe something like the "Gumball" from Rhino3D or the usual rotation ball widget would make it a lot more usable and user friendly. No idea how to make the transformation matrices more malleable than just a bunch of values though.

Very nice visualization and pretty intuitive! I also liked the explanations, neat way to understand the different operations.

This is really neat! I could actually see this being used in schools - especially the matrices feature.
