Penguins, start your engines. If you watch the Indianapolis 500 on TV this Sunday, look closely at blue No. 77 car and you might see a penguin running at more than 250 mph.

Two enthusiasts have taken it upon themselves to make Linux a household name by organizing a grassroots effort called Tux 500. It is aimed at raising money to help sponsor an Indianpolis 500 race car operated by Chastain Motorsports.
