As said in other pages of this site, Ultramundum contents will be organized in ultravision channels, very similar to those of classic television, but with a big advantage: they will be three-dimensional and interactive. Ultramundum will have a rich collection of ultravision channels, but the first and more important will be 4DGea, the model of our planet in four dimensions. Any place on Earth will be explorable and it will be possible to visit it not only in three dimensions but in any period of the past. From egiptian pyramids to the Midway battle, fron the streets of Cesar's Rome to the Paleolytic, each uman being will be able to explore in any moment our planet, in any place and in any time. 4DGea will became the greatest work ever done by mankind, a four-dimensional book whose pages will contain everything we know of our history, everything of our science, everything of our culture, everything about our endless adventure.

WHAT WILL BE POSSIBLE IN 4DGea?
Endless places will be open to visit, places that today are closed or not available any more.
We will be able to participate to sacred gatherings held every four years in Delfi, inside the temple of Apollo at the roots of the Parnasso mountain, walking among the crowd under the sun.
We will be able to walk in the gardens of Deir el-Bahari, near the kings' valley, dedicated to he Hatshepsut queen and famous for the perfumes of its plants, irrigued by the Nile.
We will be able to see the rituals for Quetzalcoatl held on the pyramid of Chichen Itza and walk in the twenty square chilometers of buildings of the last Maya capital.
We will be able to see the thirty monuments of the wonderful libian colony of Leptis Magna, edified by Settimo Severo in the first century AC.
We will be able to breathe the sizzling mountain air in the streets of the hidden Machu Picchu, built over the two thousand meters of altitude on the Ands and then misteriously abandoned.
We will be able to explore Angkor Vat in Cambogia, a gigantic complex with seventy-two religious buildings where the primitve induism was blended with the buddism in a surprising sincretism whose ruins today cannot even be visited not do destroy them.
And then we will fluctuate in the primordial ocean, walk on the ancient supercontinent, Pangea, before its breaking into the continents we know today, be present when the indians sold Manhattan.
The list of possibilities in endless and fascinating, like all Earth's history.

ISN'T IT A TOO ABITIOUS PROJECT?
Obviously is something gigantic, but we think that there will be many participants. In a way similar to that of the open project Wikypedia, everybody will be able to insert new elements. Think, for instance, about those people that create models of the most important battles with passion and love for details: how interesting for them will be the reconstruction of those events in a perfect model, on-line, accessible by everybody and really long lasting.
In the same way, many school researches and works will be inserted inside this project, instead to be lost and forgotten. All these data will became a gigantic asset available to everybody.
UltraPeg allows for modular construction. So 4DGea will grow a piece at a time, like an endless encichlopaedia where new sheets will be added one after the other.

WHAT ARE THE ADVANTAGES?
the possibility to visit the history of mankind, to use the Brunelleschi architectures, as well as the paintings of Giotto or the streets of Praga in 1800, to create new contents, show ideas or simply for enjoyment.

THERE WILL BE SOME COMMENTARY?
the idea is to provide for multiple on-line guides, automatically activated when the user approaches an alement with a description available.

BUT IS THERE SOMETHING ALREADY DONE?
all Foundation projects, even if sometimes with different names, are inserted into 4DGea, so there are many elements already defined.

HOW CAN I COOPERATE?
registering yourself and/or proposing some content, there is space for everybody.
