Bob Patterson visualized the Global Lamda Integrated Facility (GLIF) in 2008, using a base image from NASA and data complied by by Maxine Brown of the Electronic Visualization Laboratory (EVL) at the University of Illinois at Chicago (UIC).
GLIF is "an international virtual organization that promotes the paradigm of lambda networking. GLIF provides lambdas internationally as an integrated facility to support data-intensive scientific research, and supports middleware development for lambda networking. It brings together some of the world's premier networking engineers who are working together to develop an international infrastructure by identifying equipment, connection requirements, and necessary engineering functions and services. GLIF "participants are National Research and Education Networks (NRENs), consortia and institutions working with lambdas."
Funding to support this visualization was provided by GLIF and US National Science Foundation grants # SCI-04-38712 to NCSA/UIUC and # OCI-0441094 to EVL/UIC. The image here is provided courtesy of GLIF.
