 The above link is an event post I have placed on facebook - as an artist and executive director for an community arts educational gallery and foundry.  Intellectual and creative property issues are important to people like us who make their living through art and craft.  The Keystone Art & Culture Center is hosting a workshop by an expert in Copyright law for artists.  He will present the current laws and take specific questions from the audience.  Important terms these days are "work for hire" (watch this one, as your clients may end up owning part of your copyright) and "fair use" - this one may permit others to use your concept in some way - for instance the recent use of an AP photograph by the artist who created the Obama campaign HOPE image poster - a direct recreation of the AP photo.

Wanted to upload this here but it seems only images are postable...this is a 7 min video of the casting process at my studio - a non profit foundry that I founded a few years ago.  The video features a monument that I cast last spring.  Enjoy - it is fed through facebook.

I have read some archived information on building fluidized beds, but have not been successful in finding actual designs...some of the post refer to designs, but I have not seen them. Are those archived, or does anyone have a design concept that they can share.
