Thursday's Google Doodle is one of the most ambitious yet - and honors one of the unsung heroes of video game history.
- The Doodle is an interactive game that celebrates Jerry Lawson, the engineer who in the 1970's helped develop the first video game cartridge.
- You'll run and jump through a simple level that tells Lawson's story - but then the game opens up with a Mario Maker-type function that lets you build your own games and levels.
