      This tiny URL takes you to a video made by fellow who has made cardboard optical illusion models. The text is all Japanese but the music is interesting and the models are very clever, looks like marbles are rolling uphill etc. then he turns the model and you see that the parts are twisted to make downhill look uphill. The illusion only works from one viewing angle.

      Kind of long (13 minutes) but you can jump ahead. I don't know if this has shown up anywhere else on the forum. I was thinking it would be an interesting challenge to create a SU model of some of these illusions. However I doubt if I have the skill or patients to fiddle with it.

          Good stuff.

          It jogged my memory and made me think of this: http://blog.makezine.com/archive/2006/10/paper_dragon_optical_illu.html

          You can print, cut out, and assemble a few simple perspective illusions of your own.

                Great find Jim, thanks for posting it. I really like illusion tricks, and these are so well done, yummy. The marbles are astonishing 😲
                Similar methods can even become useful in SketchUp modelling - for example when trying to find workarounds like we did in this thread: http://forums.sketchucation.com/viewtopic.php?f=79&t=31069

                  SketchUp's probably the perfect vehicle for working out cut lists for stuff like that.

                    Nice one Alan!

                    Here is my version. Was struggling with the shading and concealed it with different shades of grey.
