i get it....it's the GLASS DUCK PROGRAM rather than the GLASS BEAD GAME isn't it?

i can remember my swiss grandmother showing me that church and saying that it looked like a bagatelle board...into which you could spin tops....that's wrong...not her spinning tops board...her other board...the bagatelle one...you could used marbles or metal balls....
