When I was 13 year old, I was busy playing video games and basically did not anything of my life. This young prodigy created a braille printing machine. Braille is a touched based writing system for the visually impaired.
Usually, braille printers cost around $2,000, his Lego machine is only around $350! His father invested more than $35,000 in his son's company and even Intel invested in his company.
