Google App Inventor, which will give us all the power to create apps for our Android smartphones! Me, well, I'm very interested in using it in my Interactive Multimedia curriculum at the high school level. While I haven't gotten to play with it yet, per se (you have to register and then wait for acceptance/approval), I am surprised how much it looks like Scratch! And what I love is the open, block architecture (it's based on the Open Blocks Java Library) and how it is really a continuation of the work of Seymour Papert and the MIT Logo Group began way back in the '60s.
Take a look at this simple, yet enticing video that Google posted on YouTube. Anyone else excited about the possibility of weaving this into current curriculum??
