A sideline to David's commercial work has been explorations in perspective. His first book on the subject has been widely praised and is assigned in many art courses. His paintings on spherical objects like globes and bowling balls utilizing a six point perspective method he devised himself are in many private collections, and he has lately begun a new series applying the same method to flat surfaces by map projection.
David is now at work on a second perspective book, which will include a companion disk of computer-generated perspective grids as well as video tutorials on their use.
