Distorting images

Have you ever seen drawings that look so real that they appear to come out of the page? 

They are the result of using grids that distort them. Using what we know about perspective, we can create the illusion that objects are three dimensional. This is the basis of anamorphic art. 

We used a straight grid first to create a design. The lines were numbered to help transfer the design to the next distorted grid. 

The same design was then used for the curved grid. This proved to be more tricky but very effective when viewed in a reflective surface. 

The next step is to create drawings without grids.
