The levels in the hierarchy will be represented by a unifying theme - FLEA CIRCUS.
Each job or level will be visually depicted as a flea trained to do a unique trick. The Ringmaster will exploit them all with a whip, representing the client.
The look? Vectorised clean shapes, incorporating some textured surfaces, possibly as background. Some of the lettering may be textured.
Each square is non-connective to the others and shows a view of the relevant flea employee.
Information about each flea employee will be written on a plaque (part of the picture) that explains that this is the design consultant and look what tricks he can do.
A common circus-ish colour palette will tie the pieces together.
Images, vectorised, will be mostly drawn - but it depends on the availability of free relevant internet images.
Jump, diminutive fleas! JUMP!
