Who else is pushing the boundaries for front-end design/dev open source stuff?

Hubspot are doing some awesome work with their GitHub contributions, some really interesting pieces on there. All simple, really lightweight and providing lots of inspiration from a design perspective.

Then Zurb have some great stuff in their playground and Filament were doing some great work but seemed to have pretty much stopped as late.

Interested to hear any other libraries out there that push the boundaries when it comes to jQuery/CSS3/HTML5 stuff!
