A Dual Letter Illusion and a statement! Dual letter illusions are fascinating, nonetheless they can easily be constructed following instructions form a teacher or a youtube-tutorial. This is possible even for people without any preknowledge of CAD-Design. The principle is simple and explained in the picture above. Two letters are overlayed, one of them turned in a 90° angle to the other. This gives a different writing depending on the angle of observation. We used tinkercad, a rather simple program, but nearly every 3-D construction program should work.
