And an earlier (looping) one:

The timelapse movie of the road was supposed to have gone all the way around and loop, but the camera battery went flat half way through, after photographing in the cold all yesterday...
Programming-wise, the LEGO brick connects with a mobile phone vie bluetooth, and asks a series of questions about intervals between shots, overall distance to travel and the distance between each shot, then carries on without intervention.
It's interesting to see the effects of different perspectives on the perceived speed of rotation - taking the fisheye shots from the interior pan and remapping them to rectilinear apparently speeds up the movement, even though the movie takes the same time to go all the way around!
While remapping to cylindrical perspective almost destroys the feeling to turning... :-(
