Lego bricks are indeed made for children to learn how to build and engineer. However, they can also be used for a greater good, as evidenced by a 12-year-old named Dylan Shervin who volunteered at his local animal shelter. He spotted a puppy who was born without front legs, a birth defect. An idea began to form in his mind to build this little girl a wheelchair out of Lego bricks. That is exactly what he did and the pup was able to take her first steps.
