Damn. You beat me to it. So close. The reactable is very similar to the "toy blocks", but obviously the "toy blocks" are more dynamic vs. the
reactable, which seems to be purely music oriented.
A couple of months ago I was in a Walmart and saw something similar. They were blocks like the siftables but had a black and Grey LCD display on top.
There were animated people (stick figure) and the blocks would interact with each other. One figure would open a door for example and visit another
in the next block. I would have picked some up but the cost was a bit much for me.
Those are neat! I wish we had those when we were kids. We would learn so much more faster. If every kid in the future had those then, rest
assured, the future of our Earth would be secured.
