I created this sudoku puzzle. Why did this other guy sign it?
1,693*** TODAY'S PUZZLE ***
Perhaps the best ruleset in sudoku history today from Michael Lefkowitz ("juggler)! If you've ever wanted to make your own sudoku then today's the chance but make sure you give the setter what he wants...
There is a detailed version of the rules below in case some of the terms (German Whispers/Zipper/etc) are unfamiliar.
Play the puzzle at the following link:

The version below has the extended rules:

Rules:
I need a break from setting sudokus. Could you set one for me please?
I'd like for my sudoku to have five straight lines (and nothing else):
- A horizontal Arrow pointing east (with a one-cell circle)
- A horizontal Thermometer
- A horizontal German Whispers line
- A vertical German Whispers line
- A vertical Zipper line
Each should be as long as it is possible to make orthogonal straight lines of that variety in a sudoku. Put them wherever, just not in the cells with my signature please.
I'd also like some sort of anti-chess constraint: anti-knight, anti-king, or anti-bishop (up to you, whichever works). Oh, and make sure the solution has a 3 in the corner, won't you?
Glossary: Digits along an arrow must sum to the digit in that arrow’s circle.
Digits along a thermometer must increase from the bulb end.
Adjacent digits on a German Whispers line must differ in value by at least 5.
Digits which are an equal distance from the centre of a 'zipper' line have the same sum. For odd length lines, that sum is also the central digit.
An anti-knight constraint would mean cells a single chess knight’s move apart may not contain the same digit.
An anti-king constraint would mean cells a single chess king’s move apart may not contain the same digit.
An anti-bishop constraint would mean that a digit could not repeat anywhere along the diagonals radiating from that digit’s cell.
