When I was a kid, I remember seeing in a magazine ad or on tv a building toy, in the same vein as Erector sets or Lincoln Logs, that involved bricks made of clay that were all the same size and shape (rectangles?) and a mortar mix that you made yourself. The idea was to basically build your own castle or fort out of it. This was back when kids actually had imaginations. Does anyone remember this?
