Alaina Gassler is an eighth-grader who lives in Pennsylvania. She's created a system that basically eliminates the blind spots in vehicles. Her system was built with a webcam, a 3D printed part and an LED screen that would create projections that gives the driver a complete view of their surroundings.

For her idea, the 14-year-old was awarded with the Samueli Foundation top prize of $25,000.
