Generating multiple characters from one seed

[Twist177]

The title says it all. I have been trying to come up with something to generate little worlds (81 chars) using one seed. However, I came up with a generator that waited at least a second, and 81 times 1 second minimum is... well... 81 seconds. So I would like to find out a way to generate this little world faster, by using one seed. Thanks in advance.

You could do it with multiple threads but setting it up would take longer than 81 sec. That leaves optimizing your code. If haven't seen programs with splash screens this is what they do to mask the time it takes to initialize variables like you are doing.
