This is a close-up pic of a giant leaf. I'm not sure what the plant is but it looks like a huge rhubarb. There's a lack of apparent scale in this and I think it almost looks like a satellite photo sometimes.
There is another photo of rhubarb on this site, you should check it out. This is very awesome, and I see what you mean about a satellite photo. It does almost look like a map.
This reminds me of my recent flight to San Fransisco. Very similar to the suburbs from the air except that it wasn't this green. Great macro shot indeed.
THis is really cool. I definitely see what you mean by a satellite map, but to me, the longer I stare at it, it starts to look different. It almost looks like an aerial shot of mountains. The shadows give it some depth. But you're right...without an explanation, we'd never know what the hell it is! Very neat.
