David Merrill talked to TED about the creation of Siftables blocks. These smart interactive blocks, know how to interact with each other. Say goodbye to the blocks that you used to play with. Could your blocks play scrabble, create music, assist in changing the ending to a story? After I saw this on my TED podcast, I was blown away. If you were wondering what to get me for Christmas this year then look no further =) What else would you want these blocks to do?
