I realize I’ve been working with PHP for too long when I get an idea like “I wonder exactly how birth rate affects population levels” and the first thing I think of is, “well why don’t I just build a PHP app to figure it out?”

This is the result of such thinking: Population Trajectory Calculator. It’s the newest addition to my Stupid Web Tricks page, and the first that’s not just JavaScript triggering an irritating pop-up.

This is probably just as pointless though, but it was a fun little exercise, and it’s starting to give me more ideas, which is always dangerous. Before long I’ll have built a web-based version of Oregon Trail.

I’m not kidding.

(Well, OK, I hope I am.)
