I don't know if any of you are likely to be interested, but I've been reading up on decompression algorithms recently in an attempt to better understand how dive computers work. I intend to implement the major alogrithms in simple online applications.  I've started with the grandaddy of all the deco algorithms the Buhlman ZH-L16a. You can find the current version at: http://bsac.sijomon.com/labs.jsp Feel free to have play.

FYI. Its currentlyu set at 10x speed, so running it for 6 seconds is the same as 1 minute of real time. Otherwise to simulate a 40 minute dive it'd take 40 minutes, which would be a little boring.

I'll add a display area soon which will show what a simple dive computer would actually display.

For details on the algorithm, in a nice, not too mathematical way see: www.vvw.be/duiken/zhl16.doc
