Javascript (F)utilities

This page contains some small Javascript programs that I wrote to find out if I like the language. I don't. The language itself isn't that awful, but the flaws in the browsers make programming frustrating. One can never be sure that anything works the way it should.

Boss Puzzle or 15-game

This is a simple 15-piece puzzle, invented by some deafmute American in 1878. The idea is to slide the pieces around the board so that they end up in correct order.

Features of my version:

• The game is always solvable, unlike the most single-minded (and most common) implementation. <math>(The permutation of the pieces must remain even.)</math>
• The puzzle size and the images can be changed.
• Free. Pick the source. See copyright.

It won't get any simpler than this. Compare with the Java-monster at the official euro-pages. Besides, this works also when the browser does not support Javascript/Java. (As any potentially useful web-thingy should. Surprisingly, in this respect the "official" version also works correctly.)
