Thanks for the feedback. And for the kind words.

>The only problem is that they seem to get unwieldy after a certain point. The view of all the different tools / libraries that come with it at the end of the presentation shows that.

That view at the end does not show that they get unwieldy at all. It shows that the contextual tools were needed everywhere. If the cost of tools is so low that you can amortize the cost of a tool on the first use, you can literally throw them away after that first use. In fact that's the fate of most tools. Those thousands of tools that you can see in a GT distribution are those that proved to be reusable. Many more were not :)

There were many tools that showed some visualization. But what we try to show with GT is that there exists a way to tackle arbitrary problems. This is possible because we see the environment itself as being a language made out of visual and interactive operators that can be combined in many ways.
