Here is some stuff on a Dean Hoffman puzzle from 1978 (it's from an essay David Singmaster wrote about David Klarner) http://plambeck.org/oldhtml/mathematics/klarner/singmaster/index.htm On Sun, Mar 24, 2013 at 4:51 PM, Hans Havermann <gladhobo@teksavvy.com>wrote:
This sounds like Dean Hoffman's 1978 packing puzzle. Do a Google search to see if anyone out there is making/selling them. I got mine in the 1980s from Bill Cutler with the blocks measuring 15x18x22 deci-inches.

A friend of mine had a nice magic cube puzzle. It was something like this: a 30x30x30 box, containing 27 almost-cubes, each of which was 9x10x11. Does this sound familiar to anyone? Where would I find one?
