Info graphics are a beautiful combination of maths, science, art and instruction, all rolled into one. I love the way these graphics convey often complex concepts in simple visual ways.

'SpicyNodes' interactive communication tool

Creativity | 2011.03.16 00:08 | Posted by 스마트 안전보건


SpicyNodes is a way to visualize online information that mimics that way that

people look for things in the real world. Bits of information — such as text, links,

photos, and other media — are placed into "nodes," which are then linked together

in an appealing interface that invites exploration. SpicyNodes can be used for

everything from mind maps and content portals to organizational charts and

lesson plans. Visit our FAQ for more information.





Should you pay for SpicyNodes? It depends... SpicyNodes has been made freely

available by IDEA as a public service to encourage and support online communication

and educational efforts. Free members get a great way to share, and we want you

to use SpicyNodes. Paid memberships are designed for when you need more control.

Read why you should pay.



  • Story. SpicyNodes was developed out of a passionate belief that traditional ways

    of finding information aren’t always useful or applicable to information published

    on the Web, and that finding new information should be a fun, exploratory journey

    rather than a cumbersome chore. SpicyNodes also arose out of a core principle

    to enhance scientific, artistic, and cultural literacy by improving how people find

    and interact with online information, as well as to contribute to the information

    infrastructure of the Internet. Learn more about our story.

  • One idea. From one cool place. SpicyNodes was born at the Institute for

    Dynamic Educational Advancement (IDEA). Founded in 2002, this nonprofit

    organization recognizes the Internet’s potential to transform the learning process

    by making information accessible and engaging. IDEA is dedicated to identifying

    unique challenges that prevent the Web from reaching its educational potential,

    and developing creative, innovative approaches and technologies to solve those

    problems. You can support IDEA’s ongoing research by joining IDEA or becoming

    a SpicyNodes Organization or Enterprise member. Learn more about IDEA.

  • Who came up with SpicyNodes? A team of programmers, scientists, visionaries,

    and other creative people knew there was a better way to view information.

    They put their heads together and created the recipe for SpicyNodes.
