Coming in December the Palm Pistol. Its a 38 caliber single shot handgun made like a T-shaped screwdriver. The pistol was specially designed for people with poor hand strength from arthritis or disabilities. Or really anyone who finds a conventional gun difficult to fire. The trigger is a simple thumb push with the recoil dissipated into the palm. Great for defense but with only one shot accuracy would seem to be crucial as there may not be time to reload.
Back in June 2010, Chuck posted about a blind photographer, Rosita McKenzie, who was having her work shown at the Edinburgh Art Festival. But apparently Rosita is not unique. There's quite a few blind photographers. Enough for there to be a website devoted to the community of blind photographers, blindphotographers.org. Although the site expands its coverage to include visually-impaired photographers.
There's also an accompanying flickr group: blind photographers. I suspect most of the photos were taken by people who are merely visually impaired. That is, maybe they wear glasses. Because the photos are simply too well composed to have been taken by people who can't see at all what they're doing.
