Yesterday evening Jim Duxbury was in Crossville TN ( http://www.cumberlandwoodturners.com/ ) for a demo. Lots of tips and ideas. The guy is suffering from an overdose of creativity!
If you haven't seen his work it might be worth a look:

I liked looking through his kaleidoscope with lights inside so he could use opaque bits as well as translucent. I bought his DVD - if anyone is interested I can post my impressions later.
