I had the honour of working with the late Alan Martin, who helped pioneer the concept of inclusive light painting for wheelchair and AAC (augmented assisted communication) users.
Alan's enthusiasm for light painting was such that at times, it threatened to eclipse even my own. He was a steadfast advocate of disability rights, and an exemplary role model, running his own successful dance workshops, which were adapted for light painting a a means of not only allowing access to visually creative outlets for those whose complex special needs make it difficult to express themselves creatuvely, but also as a way of identifying appropriate bespoke switch access methods that could be extended to other devices in day-to-day use. Alan was one heck of a fella, as can be seen in this film about his early life.
You did the impossible Alan, and that made you mighty. You will be missed.
