Tommy Ly lost his right leg at 18 years old, but that hasn't kept him off the dance floor.
Ly was filmed getting down alongside Giannis Sevdikalis, who lost both his legs, at a prosthetics convention in Germany this month. Since then, his incredible b-boy skills have lit up the Internet.
As a teen, Ly dreamed of learning to pop and lock, but his leg was amputated due to a malignant bone tumor in his knee. He then switched gears and took up breakdancing.
He's just one of the many differently abled dancers of ILL-Abilities, an international dance crew that's broadening hip-hop culture to include dancers with all types of physical abilities. While dancers on the crew may use crutches or have hearing loss, you'd never guess it by their intricate choreography and high-flying moves.
