Visually Interesting Bugs

Interesting results when things go haywire.

On the left is the original on the right is what happened when the computers color map was corrupted. I prefer the right image, a bit more artistic.

The image on the right is the correct result of a mosaicing program I wrote. The other images were the initial results, bugs of course, but they do look more interesting.

If you look closely you may be able to identify this image as the distal part of the femur bone (near the knee).

Unlike digital photographs where we assume pixel sizes are the same in both directions, in medical images if you don't take into account the physical sizes of pixels/voxels you end up with images like the one on the left (the one on the right does take pixel sizes into account).

3D printing technology circa 2013 (Stratasys Objet500 Connex): on the left is the finished spine model, on the right is a failed print. It seems that this machine is not a closed loop system, or at least the sensors did not work in this case: it continued printing even though the depositing mechanism had blocked nozzles. There's still a way to go till these systems provide the reliability of current day laser printers (report a material jam which you easily clean and printing resumes).
