NEW (Jun 22 2003): Manfred The Murderer

For example, the following are tricky... All of the above have nice alternative formulations, most of which took me many years to realize or find. Here are my current thoughts on the best ways to go about them.
Here are some excellent links:

I'm currently working at Industrial Light & Magic.
