Instragrok for the past two years and am happy that it has really taken a big step upwards. Instragrok sets up the connections between different items. Here and above is a small example for Napoleon Bonaparte. What is really cool about Instragrok is that in addition to setting up a mind map, it also brings up websites, videos, images, concepts and you can even add notes. You can also get a unique url that you could give your students, or they you.
