I have illustrated at various business away-days and team events as a way of helping bring the ideas to life, and adding some cohesion to brainstorming and group discussion.
After the initial on-the-spot illustrations, I often provide more detailed and refined versions as part of the follow-on work for the companies.
A recent AA development day went one step further and, working with HeyBigMan! an animated film was created around my illustrations.
Other corporate work I do includes storyboarding, in this case for a computer animation short and whiteboard animations.
