The comic strip 'Perelman' was published by the Orlando Sentinel in it's 'Downtown Orlando Monthly' magazine for four years. Rob likes a challenge. So he decided to morph the strip from a traditionally drawn strip to something that really didn't exist before. Rob's concept was that the strip existed in the real world using photographs for backgrounds and other photos of physical objects that the characters would hold.
The characters were all illustrated. This meant that however the character was drawn, if it moved holding an object, the object would need photos of that item at angles to fit the movement. It was a bit dificult. At the time the strip was being produced in the mid-90s, digital cameras were not very available. So it was lots and lots and lots of photos. Choosing the best for the background and the objects. It was extremely time consuming. The strip ended when the Orlando Sentinel ended the entire very successful publication due to technical issues with the City of Orlando. Both wanted the strip to continue in other venues but Rob felt that impractical.
By the way, the characters reflected Rob's great admiration of the humor writers of the early part of the 20th century. Perelman was named after writer S.J. Perelman. There are also characters named after Robert Benchley, Dorothy Parker, etc.
