## n-Java

I imagine that at some point in the future, people will use special drawing and animation software to write, process and visualize proofs and concepts in higher dimensional algebra.

We had recently seen something along these lines in the context of Guiraud on Higher-Dimensional Rewrite Rules.

Now I see that Berhard Keller provides with the slides for his talk a collection of Java applets that allow hands-on graphical manipulations of quiver mutations.
