I look forward to each new version of Valentin Hristov's "origami" DeltaCad macros, featured in Carl Sabinski's "Sundial Primer" website.
Recently I have made a portable dial, based on Valentin's Bifilar macro. To see it, go to my website www.sunandshadows.net and then go to "My Home Sundials". Or, as an alternative, go to "My Virtual Sundials" and check my Declining Vertical Bifilar Dial. With a little modification to the DeltaCad macro and use of Google SketchUp, here is a virtual sundial, located at my back garden. This is a declining Vertical Bifilar dial, ( see the parameters in the webpage). One of the advantages of Google SketchUp is that you get from the model the appropriate shadows from the location, date and time and you can also get animations for the model.
