The following script generates tiles by traversing a space with the dimensions: by rezzing an object, with the scale OBJECT_SCALE, from the primitive's inventory with the time-delay DELAY between each rez.

The expected result should be a three-dimensional structure with blocks:

            BOARD_HEIGHT +z|
                           |
                           +-------+
                          /|_|_| |/|
                         / |_|_|_/_|
                        /  |_| |/|_|
                       /   +---/---+----------------->
                      /   /   /   /  BOARD_WIDTTH +x
                     /   /   /   /
                    +-------+   /
                    |  /    |  /
                    | /     | /
                    |/      |/
                    +-------+
                   /
    BOARD_DEPTH +y/

This script should function properly in an OpenSim environment. Initially it had been designed to use a loop instead of a timer. However, due to some not well-founded choices, event handlers in OpenSim are killed by default after a certain time period. They should not. Handers should not go away. Just the event that triggers the handler does, after a time period.

In order to use this script:

1. Create a primitive.
2. Drop another primitive that you wish to rez at every stop inside the primitive from Step 1.
3. Copy and configure the speed with attention to the configuration section.
4. Touch the primitive from Step 1 to start rezzing the object inside it from Step 2.

You may abort the rezzing procedure by touching the object again.
