The Planiverse is on an amazon.com list of Ten Books to Change the Way You See the World. It also contains The Design of Everyday Things, which I have also read, and recommend.

And by working outwards from the differences between the second and third dimensions, we can make certain assumptions about life in the fourth dimension:

A planet would have much more room.
- There would be a wider variety of geography and species.
- The population of a planet would be staggering by our standards.
That which is easier in 2D would be harder.
- Containers, from cups to river dams.
- Aerodynamic devices, like sails and flying machines.
That which is more difficult in 2D would be easier.
- Surgery
- Information storage
- Traffic
- Machinery
Aspects of life might also be in the opposite direction.
- There would be much less respect for the land; littering might not even be a crime. One could build anything anywhere, since there would be so many ways to go around it.
- Social norms might be looser.
- Predatory life forms might have less incentive to evolve.

I'd better not think about it too much longer, or blood will start to shoot out my ears.
