Mike Glazer's Programs for showing normal modes in 1d and 2d.
This program is for showing the normal modes of a one dimensional chain.
This program is for showing the normal modes of a two dimensional crystal.
The simple instructions: download the zip file, uncompress the
file and it should just work.
Both of these programs are intended to work under windows. However,
I've checked that they run fine in linux under Wine. I assume they
will work fine on a Mac using any one of a number of windows
emulators, but I haven't tried it.
These nice programs were provided by the generousity of Mike Glazer.
