I've finally re-figured out Bill Adams's stackable origami Icehouse pyramid design. I've even made an improvement or two on it. I tried contacting Bill via email a couple times and I've never gotten any response. Similar requests on this have gone unanswered, so I assume he's not contactable and/or interested any more. Those of you that want to see this design, would you rather get "pure" origami instructions or see a printable folding diagram? I already have a diagram drawn up in a Word doc file. In fact, three copies of the diagram sized to make a large, a medium and a small all fit on one 8.5 x 11" page. You can fold it so that the printed lines all end up on the inside of the pyramid. Or you can modify the diagram by coloring in the four triangles that end up being the pyramid faces and then fold the whole thing insideout (i.e. swapping mountain and valley folds). Let me know what's best for you all. Ryan
