I purchased a 10" diam by 1" thick piece of O2-free copper from Southern

Does anyone know where to purchase 6"x6"x2" copper plate?
I've tried several suppliers to no avail.
Alaska Copper said that they could cut a piece from a copper bar, but
it'd cost $300.

Click on the "Toybox" link at the site below for an assortment of applets
that includes Maxwell's Demon. The demon can be configured to be perfect or
lazy (or none). The density is also adjustable.

Another one is at
but it's pretty bland.
