Google's Project Jacquard - Project Jacquard is a new system for weaving technology into fabric, transforming everyday objects, like clothes, into interactive surfaces. Project Jacquard will allow designers and developers to build connected, touch-sensitive textiles into their own products. This is just the beginning, and we're very excited to see what people will do with it.

Project ARA - another Google ATAP project that's making a modular smartphone. I think they're already going to test this on Puerto Rico already. In a nutshell, Project ARA will allow smartphone users to swap out components of their phone (RAM, Camera, Screen, Memory, Battery, etc) to come up with a unique gadget. Imagine the early days of the PC when you could build a desktop to your specs. They've already sent the MDK to 3rd party developers so they can get the ARA marketplace up and running.
