Baron Davis started it with an online staring contest, and friends of his, like actress Jessica Alba, soon joined in.
Now you can see if you can beat Alba's stare.
Web video and social networking has now taken a competitive turn.
The Web site, called IBeatYou.com, launched in late March and features heavy hitters in both sports and entertainment, challenging the rest of the world.
Baron is an investor in the site.
Many of the challenges are physical, but voter-driven contests like lip-synching, photos and plenty of viral playfulness fill the site.
It’s the Internet’s "American Idol" meets "America’s Got Talent." However, instead of "Dancing With The Stars," you can take them on one by one.
