I found two really interesting projects relating to my design concept: one dealing with small, tangible components that interact with each other, and the other dealing with memory capture and recall.
Siftables are tangible blocks containing digital information/media that can interact with each other wirelessly by way of gestural motions, physical contact and proximity detection.
reQall is a memory aid system/service allowing one to capture, recall, remind and share information using a wide variety of platforms (text message, instant messaging, email or voice) and applications. In instances when you cannot write something down or are on the road, you can simple call reQall to say the information and the system will be able to interpret the natural language and organize your information according to the context of the reminder.
Really cool stuff!
