MakerBot: 3D printing and replication
How 3-D Printing is Transforming Everything from Medicine to Manufacturing: "The technology has the potential to alter—even revolutionize—dozens of industries, from small-batch manufacturing to aerospace engineering, from prosthetics to reconstructive surgery and beyond. Within a decade, surgeons might even use 3-D printing to build organs for transplants and to harvest new nerve cells." @parademagazine

Gapminding: Fact Based World View
"The mission of Gapminder Foundation is to fight devastating ignorance with a fact-based worldview that everyone can understand. We started the Ignorance Project to investigate what the public know and don’t know about basic global patterns and macro-trends. We use surveys to ask representative groups of people simple questions about key-aspects of global development."

Pantheon: Mapping Historical Cultural Production. From Pantheon:
"You were not born with the ability to fly, cure disease or communicate at long distances, but you were born in a society that endows you with these capacities. These capacities are the result of information that has been generated by humans and that humans have been able to embed in tangible and digital objects.
This information is all around you. It is the way in which the atoms in an airplane are arranged or the way in which your cell-phone whispers dance instructions to electromagnetic waves.
Pantheon is a project celebrating the cultural information that endows our species with these fantastic capacities. To celebrate our global cultural heritage we are compiling, analyzing and visualizing datasets that can help us understand the process of global cultural development. Dive in, visualize, and enjoy."
Infographics: Super cool graphical visualizations on a variety of topics. From Infographics:
"The Internet Map is an interactive, zoomable design that uses a combination of algorithms and the Google Earth API to display 350,000 websites as sized circles representing their overall traffic.
Designed by Ruslan Enikeev, the color-coding shows the country affiliations.
Like any other map, The Internet map is a scheme displaying objects’ relative position; but unlike real maps (e.g. the map of the Earth) or virtual maps (e.g. the map of Mordor), the objects shown on it are not aligned on a surface. Mathematically speaking, The Internet map is a bi-dimensional presentation of links between websites on the Internet. Every site is a circle on the map, and its size is determined by website traffic, the larger the amount of traffic, the bigger the circle. Users’ switching between websites forms links, and the stronger the link, the closer the websites tend to arrange themselves to each other.
Semantic web
The map of the Internet is a photo shot of the global network as of end of 2011 (however, balloons show actual statistics from Alexa). It encompasses over 350 thousand websites from 196 countries and all domain zones. Information about more than 2 million links between the websites has joined some of them together into topical clusters. As one might have expected, the largest clusters are formed by national websites, i.e. sites belonging to one country. For the sake of convenience, all websites relative to a certain country carry the same color. For instance, the red zone at the top corresponds to Russian segment of the net, the yellow one on the left stands for the Chinese segment, the purple one on the right is Japanese, the large light-blue central one is the American segment, etc."
12 TED talks that Re-imagine School:
All over the world, there's a growing consensus that our education systems are broken. These educators offer lessons in how we might re-imagine school.
For example: Ken Robinson, How schools kill creativity, Posted Jun 2006
Sir Ken Robinson makes an entertaining and profoundly moving case for creating an education system that nurtures (rather than undermines) creativity.
