Zigzackly points us to Esha, and a simple project through which you could help blind kids.
"You pay a rupee a card to get your visiting cards Braille-embossed. So, your cards can then be read by people who read Braille. And you help visually-impaired people get a little more financial independence.
You can reach Nidhi and Esha at Esha_braille AT yahoo DOT com."
