Here's a picture of a ruin somewhere with a vine or tree or some such that's been growing for a bazillion years in some jungle. I have no idea who the guy is in the shot, so I've artistically made him even more anonymous.
Here's a vine growing up the side of the building behind our production office. I doubt I'll be around when it gets to be really impressive. You should be able to click on the picture and see it in all of its present-day spectacularness.
P.S. I would have shot it with some really exciting angle of sun on it, but:
A.) The sun only hits it for about 5 minutes in the early afternoon - the vagaries of building placement in NYC, and
B.) The sun was behind some really pesky clouds during those alloted 5 minutes today.
