Thanks for posting that. While not unexpected, it is sad to receive the news.
Malcolm was one-of-a-kind. A genius on many levels, what set him part was just how much he cared. The personal effort he put into every signal mirror he made was amazing.
I spent a week at one point with Malcolm and he walked me through the making of his signal mirrors. While premium priced, the mirrors he produced probably earned him wages of pennies an hour, but he didn't concern himself with that. He simply wanted to produce the world's best signal mirrors in hopes of saving lives.
He was generous to a fault and shared his knowledge freely with anyone who expressed an interest. When we started work to develop what became the Rescue Flash signal mirror for Adventure Medical Kits for my PSP, he was happy to offer advice, even while disappointed we couldn't possibly use his own mirrors which cost more than the PSP did at the time. :-)
He will be missed.
