growing a binary tree

this is nothing else than a simple binary tree, rendered by phps gd library. it can be used as a pageview counter, because it gets one additional branch for every request for that image.

of course, the usefulnes of really using this as a counter is questionable. you don't know exactly how many visitors were there, it's slow, and the images has to be a certain size so you can see anything at all. it was more of a fun experiment.

it takes 3 arguments:

• id: the id of the tree. this can be a string to identify what to count. new ids start with 1.
• x: the width of the image
• y: the height of the image

you can use one yourself: just insert <img src="http://tree.tapirpirates.net/tree.php?id=[[yoursite]]&x=[[imagewidth]]&y=[[imageheight]]">. but i take no responsibility in anything and may remove it any time, leaving a broken image link for you. if this gets used a lot, probably i have to remove it soon, because of the server stress it produces (all trees are rendered per request).
