I just read an article about stitching photos together to make a panorama in lifehacker.com
While I was in Taiwan I took a few panoramic pictures, usually by setting my little camera on a post or something and turning slightly.
So here is a tiny 5% size panoramic picture from outside a train station.

The full size picture you can download here, it's about 25MB.
I used an open source program called Hugin. It works very well in my opinion, although I haven't used a stitching program since the nineties.
I just noticed, after I posted this, that there is a lady on the far right who's upper half is missing, and a little old man carrying a bucket with 2 clones on the left. The cloned guy in the middle was on purpose.

Someday I'll think of a use for a small cheap headless Linux box, and when I do, I'll find the link to it here. It's called a SheevaPlug. Well I should I admit that I can think of lots of things to do with it, but none of them practical.
