I found this video from the constant posterous emails Shaun sends us but it could be a turning point in exploration of my research project. The stylus cap is everything in terms of functionality that artists I have interviewed are looking for. It mimics real life drawing through the attaching a cap to an every day pen. It allows concepts to be drawn out quickly and altered quickly. It can also be a key tool to a design agency as the concepts can be send on quickly for effective, instantaneous communication.
The design of the cap gives the user control for a more precise drawing than using your finger tip as it can be too chunky to create detail.
