"Close Encounter"

My first trial run of a programmed building spiral was a bit too close for comfort! One commentor quipped, "I read an email while passing the 7th floor!" I plotted the spiral while zoomed in close on my Nexus 7. I did not realize just how close this was until I had a chance to watch the video. Whew! The spiral has since been adjusted. :) Watch at 1/2 or 1/4 speed to see this dramatic close encounter in detail!
