I was looking for a thermometer to put on a website for my father (he runs a local health centre foundation) and I couldn't find one that didn't suck. So I made one.
If you have a secure site (using https instead of http), you can just change the URL to https instead of http. It will just work.
Feel free to use the link to generate an image on your site:
<img src="http://xdal.org/thermometer/thermometer.cgi?goal=1.0¤t=0.56&asOf=Aug/25&suffix=Million&unit=$"/>where "1.0" is the goal, "0.56" is the current amount, "Aug/25" is the "as-of" date, "Million" is the suffix to use and "$" is the unit of measurement. If you happen to be really successful and surpass your goal, that is handled too. The unit can be any valid html string, including special characters like £, €, etc. Just be careful to properly URL-encode such things.
This was created using the gd library from Thomas Boutell. I have been asked by a number of people for the source, but most are scared off by the fact that it is C++ :) (Sorry, I don't use things like PHP). However, I would rather have a better thing for everyone to use, so you can also send me feature requests. I'm usually pretty responsive about these things.
If you do end up using this, I like the idea of post-card ware... so drop me a note and I'll tell you where to send one :) ... but I also like the idea of using stuff like this with no strings attached... so only send one if you want to.
This is a (somewhat) complete list of the things I'm working on adding to the thermometer. I work on this when I have time, but I'm a busy person, so that's when I'm inspired :) I'm usually pretty quick on the simple things.
Below is the number of thermometers generated in a 5-minute window.
