Every time we worked on the exhibition graphics we ran a mouse-tracking app which then generated one of these images at the end of the session. This picture captures 1.75 hours of work.
Lines show where the mouse travelled while circles document when the mouse was still. The largest circles were generated when we were typing emails to the client, on the phone with a printer or looking at paper samples. This images shows 2 hours of work.

The art for the final poster was a composite of all 12 working sessions layered on top of each other.
