Can clients be arranged in some fancy ways rather than on a plane? E.g., a cylinder, a torus etc.

For example, if I have two clients at the left and right side of the server, like this:

	client L	server	client R

Then I can switch to client L by moving the mouse to the left, crossing the left edge of the server's screen, or switch to client R by moving the mouse to the right.

Consider the situation that I want to move from client L to client R, I'll have to move the mouse from client L to the right, passing the server, then to client R. This is not so convinient.

If we can makes the canvas be a cylinder, we'll be able to switching from client L to client R by simply moving mouse to the left screen edge of client L, and vice versa. If the top and bottom edge of the canvas is cycling, we'll get a torus, which would be very cool.
