This shape could not exist 3 dimensionally.  It is an impossible shape.  The principle is much like MC Escher’s famous staircase.

For some time I have been interested in using paper as a medium.  By experimenting with color and shape you can take something that is essentially 2 dimensional and create a 3 dimensional quality.  Not only that, but you can influence and change perception with color and form alone.  This grouping of images is aimed at playing with ideas of how we perceive color and shape through optical illusions.  Most of these are based on famous illusions but I have re-interpreted them through paper cutouts.  There is no photoshop. They are all constructed of cut paper and then photographed.

These two triangles are made up of the same pieces of paper.  When rearranged one exhibits a gap along the bottom edge.  Yet, they are the same size.

If you stare at this cube it will re-orient itself.  A small cube may either appear to be sitting in the bottom corner of a cube or it will appear to be a bottom corner missing form a cube.

If you stare for a bit the cubes will simultaneously re-orient themselves in depth. 

Move your head or screen up and down and you will perceive movement.  

All the lines in the checkerboard are actually straight.  

Blue dots appear between the squares.
