Stepping "around" constraints to "create" anew
From Popular Science "Students' Innovative 3-D Vision System Wins Prize" here. Jacob Ward writes:
"In the end, however, we chose the entry from Tsinghua University, China. Five students there built an entirely new 3-D imaging system. They conquered the classic glasses-or-no-glasses problem by simply stepping around it: instead of a conventional flat screen, they built a four-sided glass enclosure which displays the four sides of a simulated object. The system scans an object on a turntable, acquires the image data, and reproduces it by projecting the image with four projectors onto four panes of glass. Walk around the simulated object on display, and it’s like walking around it in real life. In addition, the system recognizes gestures, allowing you to rotate and zoom in on an object with your hands. You can imagine the implications for medical analysis, enhanced teaching, point-of-sale displays, and telecommunication.
The thing that blew my mind, however, was the sheer discipline of these kids in dealing with costs. They had developed several alternative systems, they told me, including one that used a rotating mirror and a high-speed projector. But they had given themselves the goal of keeping the thing cheap, and this was the cheapest workable solution."

Science Magazine's Visualization Challenege 2008
Science Magazine and NSF joined together to conduct The International Science & Engineering Visualization Challenge 2008. One of the great achievements of technology in the recent years has been the ability to communicate complex information and ideas through visualization. This effort highlights the progress through the years as you may see in the links to the previous five Visualization Challenges. Here is an excerpt from the site:
"The winners -- in categories including photography, illustration, informational graphics, and multimedia -- captured the crystalline beauty of diatoms, the expanse of the human circulatory system, a fairy tale tea party re-invented, and the dynamic life of a plant cell."
See the visual presentation of the Visualization Challenge 2008 here. I also recommend listening to an interview with Alisa Zapp Machalek here - one of the judges of the Challenge.
