A blind Indian engineer, who currently resides in the US, solved a Rubik's Cube nine months after he first started the puzzle.
Sameer Doshi from Illinois, who lost his eyesight after he was given an incorrect dosage of steroid drops during cataract surgery, cracked the difficult puzzle last week, the New York Daily News reported.
The 32-year-old taped velcro, plastic gems and Dora the Explorer stickers to the different colours, and used his sense of touch to try and solve it.
With his wife's help, he put up the images of his feat to Reddit, which went viral.
He wrote on his account that he is planning to run for, and win, a seat on the Illinois House of Representatives.
