It all happened in an instant.

When 19-year-old university student Feross Aboukhadijeh heard about Google Instant last week, he decided to build a video version of it - YouTube Instant.

How to get a job ... fast. Feross Aboukhadijeh's instant search was an instant hit with YouTube boss Chad Hurley, inset.

Technology giant Google spent years building its new search Google Instant - which predicts what users are looking for as they type.

But in three hours, Aboukhadijeh had finished his YouTube version and posted the link on Twitter.
