Acknowledgements

Thanks to the many students I've had in the past. Much of what I know I learned from you.

I should mention a few in particular.

Sarah Nicholson. That reader than which no more careful can exist.

Trevor Wetzel. He taught me more (much more) than I taught him

Carl Landskron. An artist who also happens to code; a inexhaustible fountain of ideas.

Om Patel.

Jack Smith.
