Interfaces, Topology and Magic

I saw this at the Teaching College Math blog some time ago , but thought that Doug Peterson might blog about it, since he is fond of quoting Arthur C. Clarke:

Any sufficiently advanced technology is indistinguishable from magic.

This interface uses an "inspired hack" inspired by topology. It is fun to hear such a bright person talk unassumingly about his work too.



I think students should see and hear stuff like this.
