Some assignments that I did for the class Creative Geometry. Quite a simple, no-stress class with a nice teacher and a lot of free reign over the kind of work you create.. Great class especially if you like graphic design.
Using fractals to create a landscape with the help of a program called EasyFractals... great for coming up with random patterns. (Painted over the image generated from the fractal program in Photoshop)
Enter the 4th Dimension
we also did Celtic knots and Illusions, fun stuff! But I'm not so happy with the work that I came up with for those topics. Maybe will revisit them in my own time.
Mighty Optical Illusions is exactly what it says. Pretty good reference.
