What: Blow up Bombay street photo exhibit, visit www.blindboys.org or the Facebook group here, location TBD, free.

Why: Because for one day, these guys will turn Mumbai streets into a photo gallery where you can display your own pictures and browse through almost 3,000 prints. Find any you fancy? Take them home – at no cost. Seriously!

When: You want to have a (Canon)ball. Saturday, May 22.
