There's a belvedere, at least that's what they call it. You go up there and see out over the river. it reminds me that I've always wanted a camera that could take panoramas -- about one or two degrees high and 180 or more decrees wide. I'm told there is software on some cameras that allows you to zoom into the distance, then turn the camera 180 degrees or more, and it tracks the movement of the image in order to integrate it into one very wide image. I think us hackers could have a lot of fun with a consumer-grade camera whose ROM was reflashable. Especially if it came with programming specs and (for safety) it wasn't necessary for the flashed ROM to contain the flashing software. Or maybe just if it could be made to boot from the same removable SD card it stores pictures on. If only the N800 had a better camera it could be used for this.
A conversation once turned to digital cameras, and I expressed a wish that the camera could use logarithmic coding for intensity, and a photographer there said, "No you don't." I wanted to ask him why, but conversation turned to other subjects and I couldn't get a work in edgewise before he left. There are algorithms involving random numbers that make this possible without much loss of fidelity or storage space. Something I'd like to program if I had access to the raw photoram data as it came in.

Yes, you do want logarithmic coding. 16 bit floats are the datatype du jour, there are now monitors that provide tilewise floating point output (the trick is that they use a controllable low-res LED grid for backlight, with carefully designed diffusers), and JPEG gets some new tricks in the new revision. Now we're waiting on the cameras. As to the panoramas, there are really pretty good algorithms that don't rely on camera assist, at least when the picture is not too boring, and I think some of them are floating around in open source land....
