Some walls can be windows. Into our world we can hardly imagine the exquisite details of the stone base’s craft, the mind bending world of *freckles with the shapes may shrink but they are all the same, or the very blueprint of what we are all made of, a strand of DNA. “You can immerse yourself in your data, and you can do that in 3D. This software *and all these* will have 3D capabilities.” In this case, a churning twister, each are hard at Hollywood. “You can try to describe the birth of a tornado, in words or we have a very powerful 3D animation. I mean, the images speak for themselves.”

Measuring 14 by 8 feet, this video * is known as the Viswall. You cann’t get it at Best Buy though; you have to go Tufts University in a place called the Center For Scientific Visualization. With the support from the national science foundation, Lionel Zupan helped bring the Viswall to life. The Viswall uses two real screen projectors to display a picture four times the resolution of the best HD TV. Four times! Faculties and students from many disciplines use it. For example, a surgeon developped a software so her students can practice their technique without cutting any tissue. “I can feel the texture itself. And I can change instruments. So here I can actually cut so I’m gonna try to grab the tumour.”

Mathematician Boris Hasselblatt went to the wall to get a fresh view of a model, therefore cast the population growth of certain animals. And even though he has studied this for 20 years, when he bounced things off the wall, he saw something here he’d never seen before.

“What apparent at this scale with this resolution on detail and been at eye height as well, is that all the curves of this wall seem to be meeting right here. It turns out those curves indicate chaotic conditions. That, I think it the one of the great things about this wall, that it in fact will get people to see things that are otherwise hard to see. * and animation are just scratching the surface of the wall. Imagine what it will be like when we can get one of these babies at home.
