I recently posted a timelapse YouTube video documenting the installation of the roof rails for Aldrich’s new observatory. It turns out I made the timelaspe with insufficient frames and the video happened in the blink of an eye. I used the Youtube video editor to stretch the length by about 8 times. The resulting video is quite surreal with people seemingly appearing and disappearing through walls and etc. While it gives the impression of the work that was happening I thought others might simply like to click through each frame or view them in a slideshow.
