Anyone looking for a graphic interface for controlling the arm in Linux (or potentially other platforms) should take a look here:

Code developed by user Skimater and posted in one of the comments here.

A quick update:

I've obviously not been on for a while.  The USB robotic arm project has essentially stalled, mostly because I have nothing "useful" to do with the arm.  I think without combining it with some clever machine vision stuff its not going to be much use other than as a pure gizmo/toy.  It was however fun trying, but I'm too busy with other projects right now to focus on this.  If anyone does have any problems etc with the code I've written I am happy to see if I can help though.

Hopefully there will be some more interesting Python projects in the future which will let me resuscitate the blog!
